Old man comes up to me at Tim Horton's.

Starts conversation while Jon is in the restroom.

Jon returns.

Man says jokingly, "You probably don't like it when other men talk to your wife, huh?"

Jon responds in a tone I have never heard until now: "I usually discourage it."

Man skididdles away in fright. 

*Yeah I don't think he was expecting that! Woo-hoo, Go Jon!
