you were just shopping for groceries like you normally would, you were feeling good today since nothing bad had happened.. until you went to check out your food, the cashier was hot but.. his personality not so much. you were asking questions until..

"COULD YOU SHUT UP?!.. my god.."

he looks at you in frustration and starts aggressively scanning your food, you were a little hurt, maybe this wasn't how he really acts..? maybe he was having a bad day..?
