Mad Jock you might be amused by one here. Told we would arrive back at our own private strip at "about 1800hrs" I was informed "You must not land until I arrive". So I says 1) how will I know you have arrived? 2) if you are late what happens when I run out of fuel? etc etc. Up steps Sgt. who says to youngster "Go away and when you have learned we are here to serve, you may go outside once more" Well that was the gist of what he said anyway. Job done everyone happy
