For some strange reason you turn right instead of left when exiting the en suite bathroom in your luxury 5-star hotel room and end up naked in the corridor locked out of your room at 0330. Do you:
A. Sleep in the corridor.
B. Knock on a fellow crew member's door and sleep in his spare bed.
C. Use a fellow crew member's room phone to call reception for assistance.
D. Grab the corridor fire extinguisher, hold it in front of you and creep down to the reception desk to get a spare key whilst an entire civvy flight and cabin crew arrives to check-in behind you at the desk.
