A story I heard second hand, but it is worth passing on and I really hope it is true...
Day 1 of the Airshow at a base not far south of Lincoln, a young-ish chap turns up at the gate in a passable impression of an airman's uniform and tries to get in without paying. The guards rumble him immediately, but decide to pursue the matter. A call is made to the SWO, who obligingly delivers a massive b*ll*cking to 'SAC Walt' for the standard of his shoes, his non-regulation haircut etc etc and then invites him to join a work party to sweep out one of the hangars.
