Good for you, bcgallacher. Wish I'd been able to do that.
I remember one guy who would shake hands and introduce himself to a two-ring First Officer, but would cut the other bloke dead if he was a one-ring Second Officer. Having flown with him many times, and been ignored, I did a trip with him a few days after putting up my second ring and, guess what? Yes, he shook hands and introduced himself - as if we really had never met.
Another guy introduced himself with the immortal line, "My name is Captain ******. You can call me Sir."
Oh dear...........don't get me going..........must take my pills.
