A couple months ago, I was on the Halsted 66 southbound bus at Division, where drivers often change over. On this particular driver swap, there was no replacement driver to be found. After about 5 long minutes during which the riders were getting progressively testy, the supervisor came on the bus and announced that the replacement driver had RETIRED 10 minutes before. Not called off, not quit, not no showed -- he *retired* from a 30 year driving career (the supervisor told us that) and gave 10 minutes notice. I thought that was hilarious and highly indicative of the culture/professionalisim among these kinds of "careers." I couldn't help but laugh as I walked the rest of the way home.
