Was I right or wrong?

So I'm sure this will turn into a little bit of a discussion, but I had about an hour to kill on this Tuesday evening. I flew in from Dallas and spent a couple of hours at SJC - It was dead and this was right around the corner from my hotel. Stopped in a paid the cover after walking through the metal detector. Once I paid I was in the club.

I have been here once before about 10 years ago and my thought this time was the same as before. It is a weird layout. You walk in to a stage and room with some tables, no one was sitting at these tables except for a dancer or two. As you keep walking you pass the restrooms another sitting area and come to a long bar. The bar was hopping and had a lot of customers and dancers standing around. I tried to get up to the bar and it took 2-3 minutes to get service. You keep walking deeper in the club and again you get another seating area and then the dance area. The dance area is table and cubicles that provide a minimal amount of privacy. The lighting is a little darker which is nice to compensate.

After walking around and getting my drink I sat in a row of tables and chairs right by the bathroom hallway. I was almost immediately approached by a smokin hot cuban named A*****. She was short haired, light skinned and had a phenomenal body. She asked if I wanted a dance and of course I jumped on the opportunity. As we go back to the cubicles she sits and starts dancing after the next song begins. During the first song she is giving crazy mileage and decides to try and unzip my pants. I stop her and told her "maybe, but not yet" and she obliged and continued to dance. The mileage continues after the next song starts and by the end of the song she again starts unzipping my pants and getting to work. I ask her to slow down and she just goes to town. After the end, I wasn't complaining but here is where it turned. I gave her 3 dances X $20 and gave her an extra $100 tip for the fun. This is normal and maybe a little generous from my experience. She tells me that I owe her $200; I smiled and said no way, explained the amount that I gave her was sufficient and she should have talked more upfront about her price. After going back in forth I finally told her I would give her $20 more which she snatched out of my hands and then told me she would go to her manager and tell him she gave me 10 dances and I refused to pay. I told her to go ahead, I hadn't even been there long enough for 10 dances. She stormed off and left to the office and I decided it was a good time to get out of dodge. I left without issue but man, was I wrong? $20 is only $20 but the principal was what was killing me.
