Hate to do this, but I'm gonna disagree a bit with some of the advice. Don't try to date her before dating her. I've talked to girls for 5-10 minutes after first meeting them then asking for and getting their number. Talking about your hobbies up front is like trying to date her before dating her. Besides, if you're on a date, the trick is to get her to talk about HER not you. YOU should actually remain a bit of a mystery.
A real DJ knows how to make a girl feel comfortable and show her a pleasant time. Usually that's showing true interest in HER hobbies, what SHE likes while doing something together where they can talk. This is why movies are a poor choice for the first few dates. Rather something quiet like pool, bowling, mini-golf or some other movement/action date are best.
Walk in there, smile, and say "Hey, what's your home phone number?" Regardless of what she says, she'll be very complimented. After asking that, just stand there and smile while you listen to and feel how she answers. If all you can think of is how she'll shoot you down and you'll stand there with your d*ck in your hand speechless and awkward, then maybe you're in the wrong line of work. If she doesn't immediately get a piece of paper or ask if you have one, or she asks for your number instead, just say "Okay, instead of your home number, I'll have a triple Latte' to go please" like it was no big deal.
Can you do that? Yes, you can. Now stop pe*ing on your shoes and get out there to find out once and for all if you have b*lls, er, realy want to hear "NO" or never "Know".
Walk in, smile, say "Hey, what's your home phone number?" Believe me, you'll have a great conversation right after that, just let her do the talking.
