My pet peeve deals with those extra then, extra thin, clear plastic bags in the produce section - the ones you pull off a roll, then (supposedly) open up, stick your lettuce, tomato, or whatever inside and to shut. Even after I figure out which end is the unsealed one, I find it impossible to get the bag open. And it seems like my wife is never around when this happens to me.
My solution is sexist. After struggling with the cursed thing for ten minutes or so I throw myself on the mercy of the nearest friendly-looking woman who's shopping in that section and ask her for help. She invariably gets the bag open in about three seconds, leaving me feeling even more incompetent than normal. How do they do it?
Another pet peeve: those cardboard twelve-packs of soft drinks. The package usually has some perforations on top, so if you press hard enough next to the perforations you form a handle that lets you carry the carton comfortably in one hand. My question is: Are the stock boys ORDERED to stack those cartons with the handles either on the bottom or on one side? I think they are.
