We had a guy who didnt understand English too well. Female DI comes up from behind him. He says "good morning ma'am," but didn't see the male DI on the other side of her. The male DI whips around and gets in the guy's face saying "good morning ma'am? I dare you to say it again." Not understanding English too well, he heard "say it again" so he did. "Good morning, ma'am!" right in the male DI's face. It did not end well.
