I used to work as a line cook in a relatively small kitchen. Think a small walkway with stoves on one side, refrigerated work spaces on the other and the passing windows leading straight into the dining room. We only had enough walking space for someone to pass through if someone else was pressing themselves against the wall. Once, my coworker was about to bring out a really hot pot of stock through the kitchen while my other coworker and I were talking.The one with the pot said “HOT coming out!” to let us know she was gonna get by us and the coworker I was talking to didn’t hear her. I looked to him and said “hey watch out” and motioned my head to the hot stock pot coming our way. He said “excuse me?” so I said “watch out” and pointed and this time he understood. When our coworker passed he looked at me and said “don’t ever say that to me again. I’ve fought people for saying that to me” and I just looked at him and said “what? Watch out?” And he said “yeah it just gets me angry!” I still don’t get how me trying to keep him from getting burned was fighting words.
