Sam Loomis: You never did eat your lunch, did you?
Marion Crane: I better get back to the office. These extended lunch hours give my boss excess acid.
Sam Loomis: Why don't you call your boss and tell him you're taking the rest of the afternoon off? It's Friday anyway, and hot.
Marion Crane: What do I do with my free afternoon? Walk you to the airport?
Sam Loomis: We could laze around here a while longer.
Marion Crane: Checking out time is 3 P.M. Hotels of this sort are interested in you when you come in, but when your time is up... oh Sam, I hate having to be with you in a place like this.
Sam Loomis: Married couples deliberately spend occasional nights in cheap hotels like this.
