There's this gorgeous girl who works at a local grocery store who I'd like to get to know. The only time I have a chance to interact with her is in the check out line. I want to know if anyone has ever had any success in this kind of a situation, and if so, how they did it. I've already developed a good rapport with her, through smiling and making her laugh, but I don't know how to progress it further with the short time span that this kind of situation entails. Do I try a direct approach, maybe asking, "What does it take to get your number?" Or something more subtle? Thanks in advance.
