Protip: Don't ask women out when they're at their place of employment. It's a really hard place to put them in, as they have to be professional to you as a customer, even as you're trying to get personal with them.
I know but that's the only place I ever see her.
Also, I asked her out before the lunch hour rush so it's not like I was being a big hindrance to her job or anything.
Make chit-chat and such, see where that goes. It sounds like she noticed you, and noticed that you hadn't been around; that's good. But did you speak with her much, or just ask her out, outright?
Here's how it went down:
I ordered my food (a salad to go), I asked her how her day was going and after she made her response I followed up with a: "Good to hear your day is going well. Also.. hey, whenever you're free, you want to get together sometime?"
And her response back was essentially: "Oh, that sounds nice but no thank you."
Me: "Oh okay. Well I hope you have a nice weekend."
Her: "Thanks."
And then I sat down and waited for someone to bring me out my food. And then once I got my salad I got up and left.
Anyway, unless she made a face of unmasked disgust, you may still have a chance. Just talk with her, and realize that because she's already said "no," there's no pressure to be charming or anything. Just be yourself and talk naturally.
I didn't sense any disgust from her but at the same time I didn't sense any interest from her either.
And at this point I don't really care if I have a chance or not because I'm already thinking about other girls that I could ask out at my university when I get back there for my fall semester.
I can't afford to stay hung up on one girl this year because of that stupid bet I made in GAF's drunk thread. haha...
