There's a post on the International Sex Forum (I think) in which if it is to be believed a bloke picked up a WG on the Oranienbergerstr. in Berlin, there were actually 2 of them back at her place, got his money then started saying he had to pay extra to see her tits etc, he said that at that moment he really felt that having sex with her would be the most privileged and desirable thing he could ever accede to so he gave the other girl his bank card to get more funds out. Of course he didn't find out till later that she'd drained his account, what did he expect? This was in the E100s though.
