I screwed up with dancer who wanted to be paid first

I screwed this trip up. I ended up going on a Monday evening which happens to be there $10 dance night. I always try to avoid $10 dance night because it's just too busy and the talent is messed up. This night looked like it was going nowhere but the best dancer in the club sat down next to me. Can't remember her name but she has a dishwater blonde hair and an okay body. She is extremely aggressive. Normally I take an opposite approach to most people by not negotiating before I go get dances. This way I can see if I actually like their technique or not. I really don't care if the little guy does any of the thinking.

After sitting, within 1/2 song she was offering Billy Joel and FS four 150. I figured why not but said I wanted some warm up dances which she agreed.

I paid the toll and went back. As soon as we get to the curtained area she wanted to be paid up front. I should've just said the hell with it at that point. I refused but she had me take out the money and put it to the side which I was willing to do. She told me she had been cheated after dances in the past. I know know why. I think the warm up dance lasted, maybe 30 seconds, before she grabbed cover. Maybe 15 seconds for Billy Joel and I could tell I was not going to like this. This was my mistake. It was the most mechanical mercenary dance I've had in ages.... If not ever. I said to heck with it and just finished up with FS and got out of there.
