"Broken ATM" scam

I went to Mynx a few months back. It was a weeknight and I just decided to pop in. The girls weren't bad, and I was having a good time at the bar talking to a girl. She had a very fake British accent. She convinced me to go for a private dance and I said sure why not, let me hit the ATM. She said oh you can go after no problem. At this point i was already thinking with my little head. She ended up taking me to the After dark side to a separate room, which is apparently more expensive. The dance was full on a couch that was pretty much out in the opened and full contact. After it was all said and done I went to the ATM to get some cash. It turns out it was broken. She gave me a pretty fake surprised expression and said i could pay with a credit card at the bar. I didn't really have a choice so I went ahead and did it. While the bar tender was running my card the girl started whispering with her. When i got the receipt there was an extra $50 charge on it. I started to complain but her response was didn't you have fun baby? I was pretty much done with the whole scene so I left. Now, if the mood so strikes me, I suck it up and drive to RI where the clubs are at least a lot more fun to be ripped off in.
