I absolutely hate it when some complete stranger, usually a waitress or a fast food worker, calls me hon'. As in, "here's your food, hon'," or "Would you would like anything else, hon'?"
I'm not your hon'. I don't even know your name. I can understand it a little when some woman in her 60s says it. but it absolutely drives me up a wall when some teenage kid at the drive through window says it.
