Situation at hand is:
You go to the local bar that you go to maybe once a month for a few drinks. They have a poker joker machine, you hit for 200 and cash out. New bartender has trouble cashing you out on the machine and calls owner which you know on a first name basis and he cashes you out and 0s out machine and pays you 200. About 5 minutes later Bartender (new) comes and pays you again. Do you Keep it? I want to know what you think.
