Don’t Make Me Call Security
I once told off a customer in a retail store for being rude and mean (she was so awful she made one of my staff cry). The general gist of what I said was, “Do you feel better about yourself after you make this 17-year-old girl cry? Was it really necessary? Until you learn to treat others with respect I do not want to see you in my store again. Leave before I call security.”
