Missed opportunity with a girl while working at a store

A while ago, I was temporarily working at another store and met someone from a different branch. We only spoke briefly—she introduced herself with a warm smile and a name that stuck with me.
I won’t mention her name here, but it’s the kind you might find in a book about trees—or on a jar of honey. Every time I come across it, I think back to that short moment.
By the end of my shift, we were sent off to do different tasks, and I didn’t get the chance to talk to her again. I never got her number, Instagram, or Snapchat—nothing. The only time I saw her again was when she stepped into the elevator to leave, and I was too far away, still gathering my things.
I’ve regretted not doing more ever since. Maybe this is just me letting go of a small but meaningful moment, or maybe somehow it finds its way to her. Either way, I’ve carried it for a while, and it deserves to be written down.

do you know what branch it was she was at? it may sound stalkerish but you could call it or even go there and see if she’s there? idk if that’d be weird though

You did the right thing. You acted in a professional way at work. That's not something to regret. It's something to be proud of.
Reading between the lines, where you should start doing things differently is how you go about meeting and interacting with women outside of work. Women that aren't colleagues. And aren't customers that you meet at work.
Friends of colleagues are fair game. As are customers that you meet primarily in a social setting that you incidently saw at work. As are all the women that have no connection with your work.
Your life should be so packed with man to woman social interactions that the women at work don't even enter into your horizon from a dating them point of view. And you should be aiming to speak and behave in ways that get results with the women that you meet. IE deploy good Game.

I don’t really see what the big loss was. It was a colleague who briefly introduced themselves.
I wouldn’t be comfortable asking for socials after something as fleeting as this.

I don't think I did the right thing, we was only working as colleagues for a day, we worked in totally separate stores so I should have got her details I'm such a moron

It's good to be professional at work to make sure that you never open yourself up to accusations of sexual harassment.
On top of that, there's the poisoned well aspect of your workplace.
If you make an unsuccessful move on a woman at work, she may well tell colleagues about it. And you're liable to get the sort of reputation where women will be pre-biased against you.
What about all the women that are at the same venues as you when you're out with your friends? How about interacting with them? In a man to woman social way, with you deploying good Game?
And how many opportunities do you miss out on, every time you stay at home, instead of going to a social venue or event?

But she wasn’t actually employed at his place of work

Do you think the HR department would overlook a report of sexual harassment because they're based at 2 different sites?
Do you think it's worth taking the chance of poisoned well type gossip circulating within the company, for this particular set of circumstances?
