And out of respect, I will never wear bars in another pilot's aircraft. If travelling, I will take them off on enterring and replace them on exiting the aircraft to facilitate easier passage though african airports.
Only put them on when I get to the airfield, and take them off as soon as I am rid of the pax.
Oh yes and did I mention :
I get naked and then place them on my shoulders before I wrap myself up in cling film and climb onto the cupboard, to pounce on the unsuspecting missus as she gets home from work.
