I remember asking about the scene in Casino where the two guys try to bang the casino out of 200k or whatever, and pesci goes over and stops them at the Cashout window. They leave without their winnings.
The answer was that they used stolen cards to get the initial chips to play with.
Thanks for that because I never understood that scene. I figured they were trying to shake down the place but it didn't make sense to go to the cashier.
