Many years ago in a very shiny hangar full of VERY, VERY shiny Andover's and Wessex's (wessi?) I was waiting in line to be called, by my WO Eng, to be debriefed on my annual F6442.
Over the previous 12 months, I had been an ace (no argument, an ace) and expected a glowing report.
I was duly admitted into the presence and spent the next 10 minutes having a one-sided interview (without coffee) in which my parentage, my cleanliness, my professionalism and my future within the RAF were put in major doubt.
Having stood for 10 minutes (doing a remarkable impression of a fish out of water) I was instructed to sign the document and get out. I managed to get to the office door (suffering from extreme shock) when the WO Eng barked at me "And send P*****N in".
"But I am P*****N" I said.
To this day, I have no idea who's F6442 I was debriefed on.
I learned about shabby paperwork from that.
