In Vegas, everybody’s gotta watch everybody else. Since the players are looking to beat the casino, the dealers are watching the players. The box men are watching the dealers. The floor men are watching the box men. The pit bosses are watching the floor men. The shift bosses are watching the pit bosses. The casino manager is watching the shift bosses. I’m watching the casino manager, and the eye-in-the-sky is watching us all.
