Last job I had before going into the Navy...cook on the graveyard shift at a Sambo's, remember those?
A friend of mine--a 'Nam vet--was a cook in the Navy. Originally assigned some other occupational field (radio and communications, I think), he actually requested to be a cook, and so they accommodated him. He loved it. He was assigned to a tanker ship that did regular runs from Subic to 'Nam carrying fuel.
Before retiring (in civilian life), he ran his own BBQ restaurant.
Having done restaurant work in high school and mess duty in the service, I agree with you--sucky work and sucky hours.
One good thing about it though, in the service, not too many folks gonna give a ration of sh!t to anyone who feeds them, officers or enlisted.
