I cashiered at Wal-Mart, and felt compelled to add my 2 cents. Cashiering is really, really awful work. "Customers" feel that it is completely acceptable to treat you like a personal body servant. They throw items at you, toss money at you, complain to you about the lack of an item in a specific size, complain your work is too slow, and then the next person says your going too fast. I'm a naturally happy, outgoing person, and would greet my customers and be snipped at because they are having a bad day. "Hi, how're you?" gets, "shitty, no thanks to this place" or other such negativity. I have also found that those who behaived the worst were those who may not have had a job in the service industry in their life, and don't understand how their behavior affects others or how poorly it reflects on them. OP, give the cashier a break! Or, novelty idea, speak kindly to her, it may be the only pleasantry she gets all day.
