Talking of Graduate Entry Flt Cdrs...
... I was 'stepping out' with a lady whose housemate was engaged to a guy on one of the GE courses. I was duly invited by my friend to escort her to the aforesaid engagement party.
Inevitably, the 'studes' at some stage were gathered round their flt cdr, who was holding forth on some subject or another and whilst the studes were too polite (afraid?) to disagree with the flt cdr's view, I had no such inhibitions and recall comprehensively demolishing his position, in what I thought was a very reasonable and polite way - this being a social event.
Unfortunately, said flt cdr took umbrage and said to me. "Don't you usually address an IOT flt cdr as - Sir"? "No" says I "and certainly not since I clocked up two years seniority as a squadron leader". I've no idea what happened next, as I just left him to sort out what might remain of his dignity and went off to dance with the lady. I did, however, feel rather a smug sh?t .
