In the latter days of the V-force, acting as a PV referee for a chum was quite common.
One bloke was asked about the sexual orientation of the person for whom he was acting as referee... "Normal, I imagine", was the reply.
"So you're not sure? Does he like women?"
"I expect so, most of us do. He goes to the same parties, where there's lots of crumpet"
"So there's some doubt?"
"Look, I haven't actually watched him having a $h*g, so that's the best I can tell you!"
"Next question..."
I pitied the poor old retired chap who turned up in his tweed suit at Brawdy to give me my initial PV interview. Summer of '76, a very hot day and the interview was to be held in a small office. I'd just had an hour at low level charging around Wales and had then walked back from the line. So I was sweating more than a rock ape at a spelling contest by the time we started. As the room was very stuffy, he had the full beneft of my sweaty flying suit and turning trousers - so the interview went remarkably quickly and he was soon on his long journey back to civilisation!
