FR: 30-Second Number-close

I was fortunate enough to score a free ticket to the Playboy Jazz Festival this afternoon (which is awesome unto itself, had a box seat with some good friends). On the way trudging towards my seat with a bag full of bottled water and Doritos I notice this cute Asian usher. Mental note for later, once I get situated.

Fast forward an hour: I'm walking back from the bathroom and I decide to keep walking towards the Asian chick. When I get there I see that she's standing next to a co-worker and it's blaring jazz music. Hrrmmm. I decide to go with a tried and true technique:

ME: Excuse me, can you help me? <indicating my ticket>
HER: Sure.
ME: Actually I just wanted to talk with you. You're really cute. :-) <point off into the bleachers somewhere, like she's giving me directions>
HER: :-)
ME: What's your name?
HER: A_____.
ME: I'm John. Nice to meet you. I know you're working right now, but I want to talk with you. What's your cell number?
HER: 818...
ME: Cool. What time do you get off work?
HER: 10:30pm.
ME: Cool. I'll call you at 11:00pm. Catch you later.

All in all about 30 seconds. Is it solid? Probably not-- I just called her right now (11:20pm) and she didn't pick up. I'll try again on Tuesday or something during normal business hours. Point being, though, is that a 30-second number-close is totally possible, given the right circumstances.
