Great place if you enjoy seeing 9 year old kids who are doing their best humiliated in public and accused of not studying the book by the Grandmaster, when it turns out the answer given is actually in the book, which was written by the Grandmaster, but the Grandmaster didn’t know what is in his book, and when this is pointed out to the Grandmaster he does not apologize, but justifies his behavior by saying he is just trying to teach manners, which ignores the point that there would not have been a need to teach manners if the Grandmaster knew what was in his book well enough to know he had already gotten a correct answer to his question. Which leads the 7 year old to say, «He may be a black belt, but he forgot the white belt question „why do you learn to apologize?“» Apparently he does not know, because he should have apologized, and he did not.
