Know a guy (my brother actually) called into a brothel years ago with a few mates late at night. He was pretty under the weather but still fancied a bit of fun.

Handed his credit card to the mamasan who then showed him to a room and told him a girl would be along shortly. Sometime later girl wakes him up and tells him his time is up. Mamasan handed back his card on the way out.

Later checked his ac and they had taken the fee. To this day he doesn't think he fucked anyone. Just paid for an hrs sleep.
