Sure, except that if someone was paying the casino with fake notes (hence, using a service without payment), they would have been in debt with the casino.
Someone is in debt until the payment is settled to the satisfaction of the parts (and legal limitations), which wasn't the case there.
Huh? I am not a lawyer or particularly knowledgeable about the law, but to my mind if someone has paid a casino with fake notes they have defrauded the casino. They do not owe the casino a debt.
If casino security was paying Wozniak to answer questions, then they'd have a right to be miffed if he didn't.
