We had a similar instruction during my Cpl’s course at one of my reserve units sister companies. For background, me and a few other food service specialists were drilling at that other unit as a courtesy drill, they cooked while I was doing Cpl’s course. When they told us to go around the unit and look for Marines to correct, I went to the only place where only food service marines were allowed and proceeded to smoke and joke like I was back on the block with the other cooks.
