You know that old saying "the customer is always right"? Well, funnily enough, it's wrong. Anyone who's worked in food service, retail or hospitality has had more than a few encounters with customers who were definitely not right. They were not even on the same planet as right. They wouldn't know "right" if it was right in front of their face, serving them a perfect meal which they sent back to the kitchen because the "potatoes were too beige."
