Way back in the 80's...
We were not
supposed to remove food from the wardroom - a.k.a. King Hall.
We were told that this was to keep the rodent population under control, and because it was "impolite" and against Navy custom to take food from the Wardroom back to your room, or stateroom in a ship.
It was widely ignored stricture, and I have vivid memories of folks carrying whole pies and cartons of milk out of King Hall and back to their rooms for consumption later.
We used to get lots of care packages from home, and we didn't have today's availability of tupperware. I can recall tossing out a lot of food because we found <gulp> mouse droppings in the boxes or packages, and occasionally a live mouse enjoying his/her last meal before taking a ride out a 7-4 window...
I can understand the rodent thing, as I am told by my own two Mids that the descendants of the mice we caught are still living and thriving in Bancroft. No food shortage there...
