Over-Reaction To Under-Cooking

In our restaurant, you pay at the counter before sitting down and eating. I’m taking away the dishes from the guests who have left. At one table, I see a pizza of which most isn’t eaten. Next to it lies a napkin, with a piece of meat on it. There is writing on the napkin.

It says: “Well, what do you think of this?”

Apparently the guest thought the meat wasn’t well-done enough. That’s fair enough, but if he had just come to me and made a complaint in a less original manner, he might have received new food for free or got a refund.
