FredACheck, you seem to have a better wording for the thoughts I already posted this morning:
If anyone allows us to use their airfield then certainly they have a right to impose some conditions, and instead of grumbling we should be happy to comply
On second thought, you have also wondered about the cause, and might well be right about size of ego being a factor.
Edit @Katamarino: it is not for the users of a service to judge if its conditions are "in place". You take them, or you leave them and fly elsewhere. Let the market decide.
