I can't speak for the others but the Airfield in Herts I had a few problems with was very near Welwyn Garden City and rhymed with "Bansclanger".
A thread that seems to be emerging here is how instructors seem to show little respect for the hours in your log-book.
Do the guys sitting there looking bored think that they are God....yes some of them do and some think that if they tell you something you have to take it as gospel.
"Don't put flaps down in the turn, you will kill us all"
"Don't clean up the aircraft on the runway, after landing checks should be done stopped on the taxiway with a checklist"
(yeah...carb heat off, flaps up)
"As you start to turn onto base leg, carb heat, speed, flaps"
I now don't bother aurguing, I try to remember each instructors particular pecadillos(sp) and fly as HE/SHE wants me to.
