A couple of years ago, I was travelling DFW-MIA in Business class on a 777. A young (non-senior?) FA was wearing a nametag. The name was, "Oh Miss". When I asked if she went to college at Old Mississippi, she said no. She went on to explain that a passenger had given the tag to her after a flight. She then said (with a smile), "This is what I get called most of the time anyway!"
She seemed to be having a lot of fun with it. I, for one, immediately saw the humor and salute her for showing some! I never thought of the scenario given by MiAAmistew. That is just scary!
