I am in town on business...

I am in town on business for a couple of weeks and decided to check out PE. The place is set up well and there were a couple of pretty hot dancers in the place. It was my first visit and I'm sorry but I don't remesber their names. I had a couple of lap dance, one from a rather thick blonde and one from a very hot brunette. The $20 dance fee was reasonable but they kept trying to get more cash. I don't opt for anything but the standard dance and was wondering what a guy can expect for the extra money? I would like to get to know the brunette better (Melissa??) and wondered if the girls do any "extras"?
