I grok frustration, anger -- nobody is perfect. Nobody is nice all the time. But reading something like this (from your blog):

>Just when I was about ready to go on a real tear and swear off niceness forever, the guy in line ahead of me at lunch behaved like just enough of an overprivileged dick that my relatively better mannered behavior resulted in the girl loading up my plate. I had trouble finishing it. So I think I will continue to be polite to folks who handle my food.

... rubs me the wrong way.

>I am nice because I believe in it as an ethic, not merely a manipulative thing to do.
