I can't believe they didn't catch it right away. I don't gamble either, but I would think those vouchers have the info on them for what machine it was. Don't they take a look at the slips to make sure no machine is giving out a ton of money like that?
You would also be running a risk if you tried to really tap it out. I'm certain they would get suspicious if they see you coming back with vouchers for $100K from one machine. Though I don't know if they could do anything if they did catch you in the act. I suppose there is some bylaw that would cover them to get the money back.
