Chef!

Chef Henri (aka Harry) was a bully. He took great pleasure in using technical terms then despising his students for not understanding. He had reduced most of them to tears at least once by the time they left. The permanent staff didn't like it either but it was just part of your education, they thought.
Then one day, someone did do something about it. Henri was found in the alley behind his restaurant, nestling on a bed of vomit, drizzled with a blood jus, decorated with saliva foam, and with his Sabatier sticking out of his chest. "Et voila! Service!"
