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

The door test
Sonny: Alright, listen to me. You pull up right where she lives, right? Before you get outta the car, you lock both doors. Then, get outta the car, you walk over to her. You bring her over to the car. Dig out the key, put it in the lock and open the door for her. Then you let her get in. Then you close the door. Then you walk around the back of the car and look through the rear window. If she doesn't reach over and lift up that button so that you can get in: dump her.
Calogero: Just like that?
Sonny: Listen to me, kid. If she doesn't reach over and lift up that button so that you can get in, that means she's a selfish broad and all you're seeing is the tip of the iceberg. You dump her and you dump her fast.
