Sounds like you did a great job. Confident, a little cocky, and good BF destroying material.
Next time you might want to talk a little longer. Most pick up gurus say that it takes at least 10 minutes to a half an hour to do a solid close where she won't flake. In a situation like that, after five minutes of chatting you can use the classic Juggler material:
You: (to her) "I'm enjoying this. You make me laugh. It
has been a long time since I met someone funny. But don't get
a big head. Anyway, I don't know what you have going on for
the next five minutes but I would like to sit down, have a cup of
coffee and chat some more."
Either way, great job. I probably wouldn't have thought of pulling out that BF destroyer until 10 minutes after she walked away
