I'm in a band that performs on occasion at CFBs (Canadian Forces Bases). We typically eat there and spend the night either in barracks or guest housing.
I have noticed that when we play for officers, dinner is like steak and lobster. When we play for enlisted, it's more like high school cafeteria. The one and only time I had to excuse myself towards the end of a concert and miss the closing number was after eating at the enlisted mess and getting explosive diarrhea.
Hey, my dad was a Marine and I take great offense at the suggestion that he ate crayons. He served in Vietnam; they smoked crayons, thank you very fucking much.
