So I have been talking with a cute waitress at a restaurant (no, not a Hooters) I frequent... Today I went in during the non-busy period with the specific task of talking to the waitress. She is 20 and very cute. We talked quite a bit. She asked me if I had any kids (I don't), among other things. She mentioned she just got into her own place. She never mentioned anything about a BF or husband and I didn't see a ring on her finger. I figure if she did have a BF and she was trying to get rid of me, she would have quickly mentioned that fact. Though I didn't specifically ask if she was seeing anyone.

Basically, I'm trying to figure out if she is interested from how she talked/talks with me, if she has a BF, and how I proceed with getting her to call, email, IM, or text. I almost did it as I was leaving, but I thought it went so well that I didn't want my AA to mess things up. How would you do these things?
