My annual Vegas ROB experience

Ok, it had to happen at some point but surprisingly enough it was in Rhino this time. Was there on my first evening visit when a mega hot brunette approached me when I was sitting down - I felt like I was Garth in that Wayne's World clip - man she was HOT. Anyway I try not to show too much encouragement as she sits down, we have a chat, you know usual shit like names, where you from etc. Anyway she asks me if I want a dance and I accept but she doesn't start at the next song but carries on chatting. Midway through the song she stands up for some reason, parts my knees and does a little hip movement, sits on my lap and drops a strap off her shoulder and talks to me through the rest of the song.

When the song finished she sits back in her chair and asks me for the $20. I am thinking WTF !! so I take out my wallet and give her the $20. From the look on my face I make it obvious I am not a happy bunny so the following dialouge comes out

her: you don't look happy?
me : why do you think that is?
her : I don't know
me: you think that was a $20 dance?
her: it's how I do all my dances
me : well if you think that's a $20 then fine
her: do you want your money back?
me : no, you said that was the way you dance and that it's $20 so you keep it
her: fine

She tehn walks off and I am pissed off about it and think to myself why should
