A little anecdote: a few years ago on one of my sorties to Morocco flew to Marrakech. Upon departure (early morning), arrived at airport to find complete mayhem. Crew have (or at least had at the time) to go through same security screening as pax. Found an official, explained I needed to get to my a/c and had no intention of waiting. Said official steered us (myself and a friend) past the huddled masses right through the x-ray scanner - past a BA crew who were standing there in their uniform finest !
Both of us were dressed in what could best be described as 'bush-pilot chic', cargoes and beat-up flight jacket. You should've seen the look on the BA captains face
Btw, no 'baksheesh' involved.
