Strip clubs and credit cards???

I just got our credit card bill and there is a $270 charge to a strip club on there. His excuse was that he got stuck with the bar tab for the 5 guys he was with. But he also said that he only drank one beer. I am finding it really hard to believe his story, I can't see anyone being stupid enough to be sober and foot the bill, nor go to a strip club and only drink one beer! So my mind won't start wondering what all can you use a credit card for at these places. I figured it was all cash based other than the bar, but my mind won't rest!!

*update*. I called the club and told them there was a dispute with charge and asked them to look up the receipt for me. The entire thing was a cash advance, $200 for a private dance and 50 in cash, the rest was fees. I called him out on it and he said all it was was a longer dance in a private room, I am beyond disgusted, heartbroken, he said he lied to protect my visual thoughts, how thoughtful!
