Jackpot! I'm working as a clerk in a retirement home's activity center. I notice Bob, one of our residents, is feeding a dollar into the change machine. ""Jackpot!"" he says as he collects his quarters. This goes on pretty much all day. Bob even came up and turned in about $100 worth of quarters into dollar bills throughout the day. Each and every time he'd feed in a dollar, we'd hear ""Jackpot!"" ring out with glee. It was awesome at first, seeing how excited he was, but it got a bit annoying towards the end of the day. He must have finally either emptied the machine, or gotten tired towards the end of my shift, as he finally stopped. The next day, when I came into work, I saw a tech working on the change machine. I asked him if anything was wrong. He says to me, ""I would hope so. The damned thing has been giving out 8 quarters for every dollar!"" Well played Bob!
