It doesn't have to be an unfair world.
A lot of schools are teaching a lot of things over a weekend spending only an hour or so on any particular skill, and seem quite proud of their high pressure teaching.
A more relaxed attitude and slower pace would include many more people who let's face it, all have different learning styles and outcomes.
I prefer a relaxed attitude, but then I guess the average customer has to feel they are getting value for the high prices charged, and everything crammed into a couple of days.
Seems it mostly comes down to money and liability. A more high pressure weekend obviosly has higher pressure, therefore more opportunity for mishaps to occur, or people not being able to keep up with the more able members of the group.
I think the attitude that if you can't keep up you can't do it , so go away, is wrong. Where would our kids be if normal schools worked like that?
No it doesn't but ( and I may have misread it ) your initial post on the other thread came across as more of a quasi/expedition type thing?? I could understand an instructors caution and reticence in that circumstance. Do I think its necessarily fair - No.
It would be lovely to have a school that has an ' all welcome' acceptance policy but as you've mentioned that would probably mean ( from their side of the fence in running it ) that they would want to increase Instructor to student ratio , have more highly skilled instructors in certain areas and have better provisions and margins built into most elements.
