Favorite stories of firing bad cooks?

I opened a new place. Had an interesting group of cooks hired in by HR.

I had some simple rules. No EarPods/heaphones, BUT you could listen to music on your phone or speaker all you wanted (during prep).

One dude tried to hide wearing EarPods. Obviously had to pull him to the side. Reminded him that he can just listen to it out loud.

5 minutes later- EarPods back in. Had a melt down when I told him to pack it up and go home. He went right to HR claiming I fired him for his sexual orientation lol
