Brilliant way to deal with annoying people

So, Husband spent a chunk of Day 1 of a four-day weekend waiting on a tow truck; waiting on his truck to be fixed; and listening to and watching an annoying man in the lobby of the mechanic's who had obviously never met a stranger. Said annoying man apparently spends many of his waking hours in this particular shop, whether his car is broken or not. After jawing at one woman, she finally got up and walked someplace else while waiting on her car. Then the man started on Michael. Not happy that his day off was being spent this way, he turned to the guy and said, "I'm sorry, but I don't speak English." The man didn't do irony. He turned and walked away. Brilliant. Try it sometime.
