I love the instant come back to those in authority.
In 1985 we were rehearsing for the Edinburgh Tattoo and were just wlkaing down the Esplanade at the end of the rehearsal. a couple of the lads were carrying their cornets, fanfare trumpets and their boxes containing their ceremonial headgear etc. There was an Army Lieutenant coming in the opposite direction and thsoe of us who were able threw up a salute as was expected. However, this idiot turned round and challenged the lads who were carrying all the gear saying "Do you not salute Army Officers in the Royal Air Force?" The response from one of the lads, an old and bold Corporal from Yorkshire was "No sir, we don't have any Army Officers in the Royal Air Force!" The cheer went up from the rest of the lads and one Lieutenant had the sense not to pursue the matter further.
