No, it doesn't. Maybe I have a different kind of lifestyle/friendships than the previous posters, but I meet up with guys for coffee and I don't consider those meeting 'dates' - they're purely platonic. Never have I got into a relationship from any of these meetings. We're completely friends, nothing more. Same with any new guys I meet, if I ask them for a coffee, I'm simply asking to go for a coffee and a chat, not asking them for a coffee so I can then ask them for a date. If I wanted a date, I'd make it clear I was arranging a date, I dunno by using the word 'date' maybe. I would only ever bring that up after knowing someone for quite a while (at least 5 months) and being 99% sure that they liked me.
Anyhow, even if the girl you've just met does want a relationship, I highly doubt she's going to sit down with her latte and say ''so I've asked you here because I think we'd be great together, we should have a serious relationship starting from today, what do you say?''. Things are a lot more subtle and slower than that. So if she continually asks you out, makes hints at going to your place/her place, compliments your body/gets touchy feely - then you can tell her very nicely and politely that you aren't looking for a relationship, but you really do enjoy her company as a friend. Of course, if you don't want to be friends with her, then don't go for coffee, decline politely. But personally, there's no use in throwing away a potential friendship just because you're worried she'll ask you out. As I said, it may not be the case, and even if it is, you can say no and still remain friends.
That's the grown up way to go about it - I don't actually know your age but I'm in my 20's now, and this is the way I deal with guys asking me out when I just want friendship, it works for me. I don't think it would have worked in my teens.
