A year or so ago I went to the local supermarket’s deli counter and asked for 3/4 of a pound of roast beef. The girl (appearing to be just out of high school) looked really confused but started to slice the meat. At a half pound she asked if that was correct. Said, no, another 1/4 lb please. Her supervisor was standing nearby and came over to help her.
My wife like to torment the deli people by asking for a third of a pound of something.
