You run into the casino and up to the money changer. The woman working there looks startled. You pull out all of the money in your wallet. It's only $80. "Give me a $100 chip." You say, handing the money to the woman. She looks at it and comments that you only handed her $80, but gives you the chip anyway. Maybe you look desperate. You walk up to the roulette wheel and put your money down on the 20. If you think about it hard enough you'll win. To the shock of everyone in the casino, the wheel lands on the 20 everytime until you end up with almost $100,000. The woman at the front counter dumps the cashinto a bag and you run back out the door.
