I spent a year at a school close to that. Near cult-like leadership and veneration of the "Master". The sad thing is that this guy REALLY knew his TSD and I would be a far more accomplished martial artist today if I had managed to stay even one more year - but I just couldn't. His manner of treating others (unless he wanted to impress them) was absolutely unacceptable in my view. However, even he would not have done what that instructor did.
