A few years ago I left ~$300 on a vp machine at Sam's Town. About five minutes later while my wife and I were at the buffet, I remembered that I had left my TITO voucher in the machine and went running back. You guessed it, somebody had pushed "cash out" and taken the ticket. I asked my cocktail waitress (they all like me there) if she saw who was playing in my seat while I was gone, and she said, "Nobody." To make things even worse, I remembered to pull my players' card and take my drink, duh.
