At this point, I'm sure most of us have heard enough horror stories of entitled and abusive customers to prove that the phrase "the customer is always right" couldn't be further from the truth.
It also seems that many of them fail to realize that the more they yell at an employee, the less interested that person will be in helping them.
But when a customer starts acting particularly irate and unreasonable, it's hard not to give in to the temptation to make their day worse in turn.
And sure, there are some workers out there who will react reflexively and face some consequences depending on how they get their revenge. But as we're about to see, it's the ones who remember their store's policies well and creatively use them to their advantage that can really bring out their problem customers' regret.
