^ The man with a mustache is blatantly thinking "Corr, I'd put an unexpected item in her bagging area." That's what all men with mustaches think.
The next time I get told by a machine that there is an unexpected item in the bagging area, I'm going to put a squirrel in the shopping bag, thus validating the whining machine's ill-voiced claims. Then I'll ask an attendant to come over and see what the matter is and hopefully we'll all have a good laugh at my light-hearted prank. That or I'll take a dump in it. It depends how resourceful / angry / fibrous I'm feeling on the day.
