The best congratulatory chat (and probably the only one), I received was from a certain AVM (D.L.) after passing the RAF CFS (plank wing) QFI course and being presented with my certificate.
He noted that I had already passed the CFS(H) course some years before, and that I was an A2 QHI.
"Well ShyT, you'll be able to get yourself a nice job in civvie street, on the strength of those qualifications......!"
He was in the process of leaving the service himself - his office was already cleared!
