im only 18 so i havent had a 'real' job yet but my biggest pet peeve from Retail and fast food are the rude ass customers who bust your balls over minor stuff. or people who get really mad over store policies and threaten you.
basicly just rude people.
its like cant you see im just a kid working here to get a paycheck and i dont make shit. so dont give me shit cause i dont make shit so therefore i dont give a shit.
