With my squadron resident on a cruiser in the 1970s, I was carefully selected from a cast of thousands to be the “Naval Gunfire Support Liaison Officer” as one of our tasks was to “spot” for the ship’s 6” and 3” guns. In order to learn the relevant dark arts I was despatched to do a course with the Royal Artillery.
At breakfast on the first morning I asked the steward for bacon, sausage, egg and beans, to be told “Sorry Sir, we don’t do beans”.
I failed to get a sensible reason for this from the Chief Steward or the Catering Officer, but eventually tracked down the Unit’s God of Catering in the mess that evening.
His answer- “Because, Laddie, baked beans are not an Officer’s vegetable”.
No answer to that!
