Re: Respect/Lack there of.
The original post is kind of vague as to what was lacking in terms of etiquette. Just saying people showed insufficient respect doesn't really tell us anything. I occasionally substitute for my sensei, so I ask Wayne Gorski, how would you expect me to act if put in this situation?
Assume that I have no prior knowledge, and little interest, in the subtler points of Japanese culture and etiquette. Though I generally know when to bow and in which direction, and all the other little dojo basics thast allow me to fit into a seminar taught by a Japanese instructor. I even consider such things worth following as a martial art such as aikido needs a behavioral code to be trained in seriously and safely, and a Japanese art existing on an international scale might as well use a Japanese code.
