Im just saying how the cc might see it. They weren't there and all they know is he authorized it. Otherwise anyone who makes a crazy purchase on their credit card can say, "I was drunk/high/had a gun to my head when I made the purchase" and get a chargeback and cc companies are not in the business of losing money because you willingly impaired yourself.

Now, the strip club? They knew what they were doing. He needs to go to an attorney before the police for that one.
