About six or seven years ago, I remember the Flt Lt who appeared to be visiting High Wycombe for the day...he had forgotten his hat and was discussing this with the gate guard, who was advising him to borrow one from somewhere or pop into stores rather than pass through the main gate hatless.
The brave fellow pressed on sans hat. Not sure what happened to him, fair game really!
I also remember my colleague of the same rank walking alongside me with jacket unzipped after lunch one afternoon (got to let the belly hang out I guess)....window of some random building opened with a b0ll0cking thrown out with it, much to my amusement....the random staff officer probably drifted back off to sleep afterwards...
