I was at the Pioneer in Laughlin and was lucky enough to win a few bux at Blackjack. I colored up to a black and walked over to the cage (10 feet away). The cashier picked up the phone that rang in the pit behind me. When the boss looked over she held up the chip and he shook his head telling her that it was OK to cash. First time I have ever seen that, but I've never gone much higher than the $100 or $500 which is very commonplace in the larger casinos that I frequent.
