Two stories going back to the mid-to-late 70s:
Tale No1:
I was called one weekend to go out to fix HMS Bronington's Type 975 radar set.
http://en.wikipedia.org/wiki/HMS_BroningtonShe came into the Firth of Forth from patrol, and me and my duty chap - Radio Electrical Mechanic "Yogi" Bear - were ferried out by boat. Yogi knew all about these radars, I knew nowt much about them at all! and he fixed it with the spares we'd brought with us. I just watched and looked officious and knowledgeable.
Meanwhile, Lieutenant The Prince of Wales - the commanding officer - was out on the Forth having a go at windsurfing! Later, when we were leaving, he shook my hand and thanked me. (I'd done nothing, but I didn't tell him that!)
Tale No2:
A while later, Bronington is alongside in Rosyth Naval Base, and my boss was walking along the jetty when he saw a young officer with his hands in his pockets. My boss was a stickler for dress and bearing, and strode over to this officer and was about to give him the: "How do you expect my young ratings to stand correctly without looking slovenly with their hands in their pockets when officers do it etc etc etc" ...................... when he saw who it was!
He turned tail!
Oh, how we laughed!
