I too find this an interesting thread.
For sure, if you judge a school by it's reception rather than the standard of it's teaching and results then perhaps it says more about the judge than the judged.
From my experience, SFC does what it says on the tin. The CPL school is there to train people not just to pass the exam but to be suitable for a career in commercial aviation. If you can't take a few well judged expletives from people who only care what standard you can attain then join the public sector.
