Listen T; my brother-in-law did eight years in subs. He said the whole culinary thing is BS. What really happened was they would re-supply in port then set off on their run which was classified and unknown to anyone except the captain. Three days out from shore the fresh supplies would begin to run out. By the end of the second week it was powdered milk and eggs and frozen dinners. That whole filet Mignon thing is made up. The worst part is they have really no medical staff on board. Just a corpsman who is trained in emergency medicine and first aid. They aren't allowed to surface for any reason. So if you had a serious illness like burst appendix you were in hot water. He eventually was asked to disembark due to a prohibition on gambling on board. Since there wasn't anything to do they would play cards. Guys would lose an entire three months of wages and return from sea broke to their very upset wives and families. He did well though and managed to sock some cash away for a rainy day.
