Vegas Double Deck is sweaty. You're going to get backed off. If you played on a card, it's possible the card was previously heated up. But, in general, I don't recommend rated play on vegas DD because it's gotten so damn sweaty (they're backing off red chippers).

Also, if you're ever backed off, don't go to the cage. ALWAYS IMMEDIATELY hit the door. Don't ask if you can play other games, don't go to the cage (they may take a better picture or try to back room you once you're out of view of civilians), just leave. Immediately.
