I had a friend who was a chef in the Officers Mess who was constantly being "hauled over the coals" for his un-Airman like qualities and demeanour by certain members of the Officer class. He would smile benignly whilst undergoing this berating and humiliation whilst being dismissed by the Officer as some kind of simpleton, however my friend knew that later that day he would be making the same Officers dinner and that "Revenge is a dish best eaten cold"
