I was on a amphib and at sea we usually had a large number of marines on board. Felt sorry for them nothing at all to do and crammed into troops berthing's that was crowded. We used to mess with them when we could. One guy put a engraved plaque on a door by the mess decks saying Ice cream shop then a hand written note saying opens at 12 today. Pretty funny prob 300 lined up waiting for it to open for a hour or so!
