its the instructors forum so no real exposure to ppl's.
A lot of these characters are actually quite pleasant to the punters and even when the business goes bust they will have a core of punters who will stick up for them through thick and thin.
The instructors etc will see the nasty side of them which is only selectively seen in the school.
I'm sorry but you really lost me there. English isn't my first language so I'm not exactly sure what you mean about punter.... do you mean "customer"? Even so, I can't make sense of the whole message.
