F3G,
I couldn't agree with you more. I don't have any first hand experience, but I'm pretty sure that instructors put their trousers on one leg at a time, just like the rest of us.
In this case I took the instructor's opinion into consideration, shouted "Clear Prop" loud enough to wake the dead, then apologised for having disturbed him. No point in letting these colonials get away with lowering standards, what?
