Really, it's not. But it's possible to be damn annoyed to have to "do as the Japanese do" when not in Japan or with Japanese people. Few things bug me like being called "Josh-san" or being bowed to when I'm in "American-mode".
Why so serious? As far as I can see, the OP gets double value -- Aikido instruction plus comic entertainment. Whats to complain about? Just relax and enjoy.
