Whenever you go to the cage with big chips they will always check for outstanding markers. They want their money back, ya know.
I was in the high limit room at Caesars a few years back when a player hit a royal and said he wanted his $20,000 in cash. The floor person went to the cage to get it, but when she returned she had a suit with her and the suit said, "I'm sorry, we need you to pay back your $12,000 in markers first."
