When I left the RAF it was refreshing to get my Mr title back
The CAA never seemed to want to help - they insisted on addressing all correspondence to "Captain xxx" when I first started flying civvy. It took some time to get them to accept that I wanted to be called "Mr". Then there was one of the ex-bobby observers in my last job who learned that it really wound me up to be referred to as Captain when on the ground, or as 'sir' at any time; you can guess how much he enjoyed pushing the buttons
