When I first started working in commercial kitchens, something I never did prior to going to college, my first job as a prep cook was strange. My supervisor/head cook and I handled the entire menu for a very busy pizzeria in a small touristown. I'm not really tall so for some tasks I had to stand on a milk crate to reach the top of the equipment, I also suffered a couple weeks of knife nicks on all fingers. One day the head cook was on some tear about I don't know what but he felt he had to insult and rant at me while I was standing on the crate with a BIG knife in my hand.
At that moment he, a not very bright individual who felt threatened by me for some reason, let out a nasty insult about my intelligence and education (I had those he didn't) while standing right next to me. I just looked down at him with "the look", then down at the giant knife in my hand, then back at him. His eyes followed mine to the knife, then back up to meet mine. At that point, his eyes got real wide and he was across the room and around the corner in a flash. When I finished my task I walked out. Found another job five minutes after I walked into the bar where most jobs were to be found.
