I recall a couple of co-workers having a little argy about a personnal matter, one of those where nobody could be right or wrong, but they still were batting it back & forth...finally in frustration, he called her by her last name (which meant to me he was ready to tell her off)...paused, & told her, "You have a nice day!!!"
His tone said exactly the opposite, & everybody in the room got a laugh...
