tacpot, I often do!
Problem is that the ground crew are employed by the aerodrome operator and from time to time some instructors employed by said operator start up with tail facing towards open hangar doors ,etc. You then get some strange looks when you query where they are parking the aircraft for starting when you ask, politely, for it to be moved to a more sensible position.
The rules at said aerodrome only permit the ground crew to move aircraft in and out of the hangar.
