No need to grab my stack of bills!!

I decided to do some barhopping today. First stop: Goldfinger. Sunday, early afternoon, there are about 12 patrons and 4 dancers. I would rate the ladies from 3 to 6 (from 1 to 10). A 4 girl approached me and I clearly let her know I was not into getting dances or anything else for now. She stayed with me and started to touch my shorts and offering all kinds of services ($150 for a BJ and $250 for FS). I declined and she kept insisting, dancing next to me and asking me to touch her ass. I bought her a drink and kept chatting with her. I finished my beer and she asked for a 2nd drink... I didn't know how to get her off my side! I told her I was about to leave, and she asked for a tip for her time. I gave her $5 and she grabbed the stack of bills I had and wouldn't let them go... She started saying she danced for me and I had to tip her more! Like she was demanding more money... I asked her to let the money go and I was going to give it to her anyway... And I did. After that I simply left. I felt like I was mugged somehow... Butterfly is her stage name. If you see her don't fall for her gimmicks to get money you may want to spend with someone else. It's not about the money, which wasn't much... It's about taking it forcefully from you.
