Regiment officer, a well known "character" famous for his flowing locks at Catterick, c 1965, was told by the Commandant (station commander) to get his hair cut. Replied in a hurt tone "But sir, the chaps get their hair cut, officers wash theirs!" Come to think of it, he may have transferred in from the army, which would explain a lot.
I remember my squadron boss (later an ACM) nearly having a stroke when three long haired blokes in flying suits came and sat down at an adjacent table at breakfast in the mess at Akrotiri. He was gently restrained from adminstering a bollocking by someone pointing out that these were civvies, a Canberra crew from the bunch at Bournemouth, I think.
