My wife worked for an airline, and one day she was verbally abused by an agent wanting a free upgrade. She received a grovelling apology after she said to him: "You obviously go through life under the impression that the person with whom you are speaking is less important than you"!

And once on a bus, she was jostled quite roughly by a guy pushing past to get off. She said: "Oh, please forgive me! I never realized that you had no manners!"

You don't mess with my missus!
