I knew a knight of the realm - while a lovely guy, he could be a bit Siralanish about it (and since he had worked hard to obtain the knighthood, I could understand why) and would quite happily use his title to improve his situation on aircraft (he was usually well looked after, knowing everyone in aviation - he did once pull the 'I know the BA chairman' at check-in when check-in were not co-operating with his polite requests - except he actually did, and the call was made and the upgrade was acquired
). Was surprised there was no 'knight of the realm' option to tick as occupation when exiting China. We suggested he try 'capitalist-running-dog-pig' - he took it in good part and opted for 'retired' instead
