Girl advice

No the first girl I just asked for her socials judging by her response she wasn't interested. Gave it a bit if space and Time and got over her. then that's when I met the second girl.

Still, the same thing is happening.
Why aren't you being more decisive? Why are you still over-analysing things?

How am I supposed to ask her out with a load of customers and her colleagues around?

Have you considered that it isn’t appropriate to?

Because this new girl is extremely shy completely different to the first one and also I haven't been going as frequentlyHow am I supposed to ask her out with a load of customers and her colleagues around?

OK, that's fair enough.
However, you say that you've been going in this shop for months, and you've had "banter" etc. with some of the other staff; so I'm assuming you've got a good relationship with at least some of the people there.
Don't you think they would be in a better position to tell you your chances with this girl, and how to go about it, rather than a bunch of nobodies on a random Internet forum, who only have (at best) a small part of the relevant information?

I don't know them well enough plus it wouldn't stay quiet and could get embarrassing for her.
I'd rather ask my friend who she's familiar with to approach her

OK, that sounds like a plan... just deal with it relatively quickly, and don't let it drag-on for months like last time. And don't get your friend to ask her out on your behalf, just get them to find out what she thinks of you and go from there. As I said, the sooner you act, the sooner you know where you stand (either way).

You say that, but the previous thread was started over 5 months ago, and in your opening line, you said and I quote:-
Given the how old the thread is, and the fact that this has been going on for "many months" before you posted. Maybe not quite a year, but if you do the maths, it MUST have been going on for at the very least the best part of a year.
OK, for the purpose of this reply, I'm going to give you the benefit of the doubt and assume you're telling the truth, and this is a different girl.
Honestly, your original description in this thread sounds almost identical to the previous encounter... you meeting a girl in a shop, you going in with a friend, her refusing to give you her contact details, you over-analysing every minute detail etc. The only real difference I can see is that previously you asked for Snapchat, and in this case you asked for her number; even that is basically "Potaito" vs "Potarto". At the very least, this shows that you haven't learnt / taken the lessons from the last disaster; and this is heading in the same direction. If you really liked her, why didn't you just ask her out within the first couple of times you saw her? She may or may not have said yes, but either way, at least you'd know where you stand... and rejections are always easier to deal with if they happen early on before you catch feelings or build a fantasy up in your head.
And did you ask her directly for these contact details or go through a friend? Personally, I would never give out a girls contact details to someone, unless I was 100% sure of the relationship between the two, and she would be OK with it. An alternative thing you can try doing is pass on your contact details and if she's comfortable, she'll contact you.
Be that as it may, this isn't a Hollywood Romcom, this is real life.
Fair enough, in Romantic Comedies, the hot babe is eventually seduced by the goofy but persistent guy. However, in real life, this kind of behaviour often screams "STALKER!!!".
Moreover, the OP hasn't said how the last encounter ended... If he asked her out and she said "No", then I would hold out some hope for success one day. However, I suspect it just petered out and this will be a repeat of the same scenario.
@Anon #1 By all means, you can prove me wrong if you say in your next post that you directly asked her out (obviously it would be best if she said yes, but the outcome isn't important for this... either way, the important thing is that you're taking decisive action, rather than over analysing a simple encounter and pointlessly making it more complicated than nuclear physics)

What can he say to find that out? It's going to look a bit odd if he says to her 'lisn do u like my friend ur always smiling at him'

Girls that work in retail will view this as an occupational hazard. It can be inappropriate because it’s not a dating context and the role is to serve and be friendly. If they’re attractive it will happen regularly and let’s face it they’re not likely to be relying on a random admirer asking them out at work. The best strategy is to flirt a bit and see if you get encouragement. Don’t ask for contact details unless you get a positive reaction. Even then it’s quite likely you’ll get blown out

That happens in every workplace though. More or less every job in the public sector u have to have good people skills and be polite.

But you’re not exposed to a stream of random strangers hitting on you as much in those environments

A few months ago I met a girl in a retail outlet . After a few more weeks of going regularly I asked for her number but she didn't give it. I may have also possibly made her feel uncomfortable but maybe not.
I met another girl who works there and had a mate with me. She was serving us on tills and we made her laugh but we could tell she was shy and reserved but she was nice and polite.
A few weeks later I went again and she was polite again couldn't really get a read on her but she gave me like a side glance like she was seeing how I was reacting.
Just recently I went again with a mate and as we were walking out she was walking towards us. She looked then started smiling. As she walked past she was smiling to herself as she walks past me whilst looking down. Initially we made eye contact but then she looked down. As she got closer she was smiling even more and she was blushing.
She is a really shy girl and isn't the type to interact in public. She's reserved
Is she interested or uncomfortable because she probably knows I asked one of her colleagues for her number

"Character development" in film terms is a euphemism for personal development in the real world.
Developing as a person is never a disaster.
What the original poster has been doing is better than staying at home and not interacting with anyone.
I think it's much better to put a positive spin on these things than a negative.
Mystery is the joint best dating coach in the World. Take his gambit from this video, and make a small adaptation to make it apply to your shop situation instead of the bar example that he gives.What he says, and the tone of voice he says it in is social genius. It's honest and open and very socially calibrated.
Don't get your friend to ask her.
Aim to be a mentally and emotionally strong guy.
What's mentally and emotionally stronger? To ask her yourself or get a friend to ask her?
Delegating is great in a business environment. In this shop social environment it's not the way to go to maximise your chances of success.
Exactly. You've worked it out yourself that asking your friend would be a bad idea.
Use the Mystery gambit from that video above.
Feel free to practise it a few times on other women in other shops / bars / clubs / street survey settings.

I know how it looks but I'm not hitting on anyone or being inappropriate. I've had a few polite interactions with someone and I'm going to try and take the next step

With respect, you've completely misunderstood what I was suggesting!
I NEVER said "Get your friend to ask her out for you"; as a matter of fact, feel free to check my post #25 where I specifically said for him NOT to get his mate to ask her out. The whole purpose of this was just to find out what she thinks of him in general, so he knows whether she's someone worth pursuing or not. As per the 1st post, the OP still doesn't know whether or not she likes him and he says she is shy... so possibly socially awkward, so her behaviour / mannerisms could be down to a number of things. Moreover, it was a suggestion in response to his reluctance to directly approach her in a busy shopping environment, where she is working (understandable); in addition to others who have repeatedly said it might be inappropriate for him to directly hit on her (a theme also reiterated in the previous thread).
Assuming his friend actually knows her & other staff, it should be natural for them to have some chit-chat from time to time. Whilst talking casually, his mate could bring up the subject of him (the OP) in a generic way (e.g. "My friend XXX did this funny thing the other day and...") From her natural reaction (and how she responds), it should be obvious what her opinion is of him (if she has any at all). If she's not interested, he can then draw a line under this and find someone else to obsess over; alternatively, if she does like him, chances are he would have naturally come up in conversations during a coffee / smoking break... it should be easy to find out if that's happened.
As for the video, personally, I didn't like it, so I (personally) cannot recommend he uses that "gambit". It sounded too much like a rehearsed pick-up line / routine (and a bit cheesy IMHO). It may work for some people in certain situations, but it's not something I'm particularly keen on, as I've yet to meet anyone who's "pulled" from a chat-up line (or similar); the people I know who are successful are casual and natural around women.
In any case, I don't think the OP is looking for a "close" right now, he just wants to know where he stands; after all, her signs are ambiguous. He's better off clarifying this with people who are there "in the mix" rather than putting it to us, who, at best, only have a partial view of the whole picture. I don't think he'll bother if she doesn't fancy him or is indifferent about him. He wrote this after you posted:-

I never said you said ""Get your friend to ask her out for you" 😄
For most of my previous post I was quoting the original poster and addressing what he had said. 😁
It's good that you and many other men wouldn't take the advice of Mystery, the joint best dating coach in the world.
The fewer men that take his advice, the better it is for those that do.
When I've followed the advice of leading dating coaches, it has worked very well.
I can't think of a better way to try to escalate things with a physically attractive woman when she's at work.
I cannot agree with the negativity involved in dismissing the advice given by Mystery in that video. A default state of positivity and enthusiasm and keeping things light is much better in many situations in life, including man to woman meetings with shop assistants.
There's a very high chance that this shop assistant's feelings are in the balance. That she could go either way. Because she doesn't know the original poster well enough. In these cases, it's generally better to assume that she's interested enough. And that the longer she spends in the company of the original poster, the more likely it is that she will be attracted and interested.
Positivity beats negativity.
Mental and emotional strength beats mental and emotional weakness.
Is it mentally and emotionally stronger to clarify what her ambiguous signs mean, or to instead proceed on the assumption that spending time with each other is the best way to go? And if it turns out that he's not the right man for her, for him to have at least enriched her life in the time they were together, before parting ways with no hard feelings?

My friend is 'in the mix'. When I've interacted with her he's been with me. He's picked up on signals from her like blushing He was with me when she was smiling and even asked me why she's smiling like that?

Well the whole thing stems from my suggestion, and given how you in particular seemed to have interpreted it, I felt it was necessary to defend and clarify what I said.
Well good for you guys, and too bad for the rest of us. There are several ways to break the ice with someone; I think a phrase involving the words "horses" and "courses" springs to mind here.
As I said, I didn't like it because it comes across like a chat-up line (style). It's something I've repeatedly said I'm not a fan of for a number of reasons (mainly because I've not known anyone who's been successful using this method... although there are other things I don't like about that whole method). I've always said I prefer more natural encounters, so it would be disingenuous of me if I were to suddenly say "That's a great idea", just because he's allegedly the best dating coach in the world.
You can create that positivity and enthusiasm you mentioned in a number of ways... such as asking about a product in the store, and then engaging in some chit chat.
Anyway, we don't need to keep going on and on about it. We can agree to disagree; moreover, the OP (et al) can see what we've had to say on the matter, and they can make up their own mind(s) whose school of thought is better / preferable (or perhaps bin us both off and do something completely different LMFAO 🤣).
