I know just what you mean, galley for kitchen, below for downstairs, deck for floor. Once, a very long time ago, I had the experience; we will call it that, of being billeted in/on a RN shore establishment, I believe they call them ships!! Anyway, it was knock off time for us, the delights of the local pub beckoned, we were all in our finest running ashore rig, whooops, Andrew slang creeping in, just to exit the base when some screaming bod comes tearing after us, you can't go out there! The liberty boat's left, you'll drown!! I rest my case. Mad, the lot of them.
