How do I ask a girl I worked with for her number?

Go for it is right! The worst that could happen is she says no. Talk about music first then ask if she wants to go to a punk rock concert or hang out at punk clothing store like "HOT TOPIC". Whatever you do, ask her out. You don't want to to have to say "what if" or even worse, she meets someone else.

It's late, but I saw "dreads" in your profile name so I decided to make this my last response of the night.

First problem in your question: acting cool. Here's some advice that will take you a long way in life. Don't ACT cool. BE cool. Yeah, the message is a little cryptic but basically it means having confidence in yourself and letting that show as opposed to wearing some fake facade that you hope will appeal to her. Trust me, women are intuitive creatures and she will see your "act" a mile away.

Sure, you blew the first chance you had to get her number, but who hasn't done something like that before? I can't emphasis this enough. You have to be confident in yourself. Try your best to develop the mindset that she is going to be receptive. I know it's easier said than done, but if this girl is worth it, you'll do what it takes.

Bottom line, dude: develop your confidence and get in there! Here's what I would do in a similar situation. I'd go in while she was working during a slow part of her shift. Pretend I didn't know her and ask "so what's good here?" Whatever she suggested, I'd reply by saying "you eat that crap? I heard only lame girls who play WoW eat that mess." After that, I could take the conversation in a variety of directions... It doesn't matter as long as she's laughing and relaxed.

I wouldn't stay long... 3 - 5 minutes tops (the law of supply and demand)... I'd end by saying "I have somewhere to be but me and some friends are getting together for some WoW. You should come!" As I'm saying this, I'm writing my name and number (or email) on a slip of paper (no cell phones). I then tear the slip in half and slide it to her with the pen. She will automatically know that the gesture means "write your number down." And just like that, I leave with the digits.

Now, do not try this verbatim. This is what works for me and my personality. The key here is to use your own strengths, your own brand of humor to create a favorable situation. Well, my fellow dread head, I hope this helps. Sorry for the long post.
