Eccentricty wasn't extant only in the RAF; I recall a RNZAF Group Captain and Station Commander at Wigram when all flying training was done there who took it into his head that no officer who lived off should arrive at work carrying his lunch and should in fact eat in the Mess regardless of the fact that they'd have to pay!
On the other hand, there was, for many years, a Works and Bricks gardener employed at Woodbourne who had a habit of leaping out from behind bushes and throwing a magnificent salute in the direction of any passing officer. Ever obliging, they always returned it!
