I've been out now for longer than I was in, but returned to a Royal Naval Air Station recently for the funeral of an old mate.
When I was dropped at the gate in the morning to collect my car, I realised immediately that I might have some bother getting in to collect it. Quite rightly too.
The extremely polite rating on the gate used his discretion and, after seeing my driving licence, and witnessing my remote key opening the car door, allowed me to proceed, in his sight to get my car.
Such a refreshing change from the experience with the security staff at a Midlands airport, whose obstructive and rude treatment blighted my last few flying years.
As for carrying rank forward to civvie street, it amazes me. I managed to put up with an ex pongo blanket stacked in the local pub who introduced himself as 'Major', until one day having to point out that rank among civilians is about as relevant as size amongst turds.
