I get you, but I think you're assuming the point was to point out hypocrisy for the sake of hypocrisy, when the actual point of pointing out hypocrisy in this case was to ask the question: "What exactly is your goal here? Do you want me to fire everyone who made fun of customer names? Because if so that means I'm firing you too. Any response to this situation will involve disciplining you too, so what are you trying to accomplish?"
