Hi all
It's a scam,pure and simple.Hit the gulls where it hurts and they're too unwitting and too intimidated to protest.I encountered it in another school where the net result was that we avoided the instructors unless we absolutely had to, which is difficult,given the need to interact with them.When the instructors began to ask what we were up to, we said that we didn't want to be charged for asking casual questions outside any defined briefing session.Eventually, it led to a group meeting with the boss to iron things out.
Scum.
