Boss: (Shouting) Little Johnny, come to my office right now.
Little Johnny: Yes, sir!
Boss: Little Johnny, I saw you arguing with the customer that just left. I have told you before that the customer is always right. Do you understand me?
Little Johnny: Yes, sir! The customer is always right.
Boss: So what were you arguing about with that customer?
Little Johnny: He said my boss is stupid and an idiot, sir!
