Last week, there was a woman shopping for accessories for her new house. She was buying a doormat and when she was checking out said, "I don't know if I want to leave it outside. I don't know yet if I have shitty neighbors. They might take the doormat."
Her male companion tried to dismiss her fears. He reminded her that it was a good neighborhood.
Wherein she dismissed his notion of niceties. "Rich people steal shit too." Then she turned to us behind the counter and said, "I'm sure you guys know that."
It was sort of awesome. Her voice was loud and the store was busy. Others heard her. It is the sort of thing a customer can say, but clerks cannot. In the fantasy world that we perpetuate, the customer is not just right, but saintly. When a regular customer is grifting, stealing, or swindling, they are in a state of denial, most likely practiced and justified to themselves beforehand.
Our Loss Prevention Professional says that 1 in 5 customers is a casual shoplifter. So someone is doing it, cause "shit" disappears.
