I haf a pocket sown on to the thigh front of right trouser leg for my moble telephone.
I have also had one four bar epaullette sown on to this pocket.
That way everyone knows it is the Captains's telephone-only may be answered by the hostess when ordered to do so slowly.

I recently flew a single engine piston aircraft from England to Abu Dhabi, didnt bother with bars or any form of uniform in the european countries, but did when crossing the arabic ones (egypt, saudi arabia etc) and I think it made a real difference, especially with security

Pulling Rank
 

I believe very senior Captains in some of the worlds leading airlines have 4 bars painted on to a certain body part to allow them to "pull rank" whenever they have the desire. Can anyone verify this particular rumour?

Nope, that is not captains. It is the engineers because the bit between the bars is pink?

I usually remove mine as soon as I leave the terminal. That said, such a process has caused me to lose them so I sometimes wait till I get home to remove as well. I place them in the same spot along with the wings and other crap so that I know where everything is before the next trip.

I never wear them into resturaunts, malls, shopping, etc. Work is work. Why would you want people in a mall or eatery starring at you anyway?
