Re: exiting a dojo
Yeah, this may be an urban legend. I've heard several times and IIRC WRT different styles (all Japanese,though). It's possible that it had its genesis in a real incident -- not at all unlikely, in fact, when you consider the foolishness that human beings get up to. On the other hand, it's not something I'd consider a likely outcome, in Japan or elsewhere, if you were to announce that you're leaving a dojo "...but AFTER this training session!" That, however, would not encourage me to do something that strikes me as stupid and tactless even in the absence of the mildest retaliation. If you're going to go, go. Don't make a drama-club production out of it.
