Oh, yeah, the classism. 
I was by myself on the roadie a week or so ago, when I passed a guy in street clothes, beach cruiser type bike, going the other direction. I gave him the little drop-bar wave and nod. I probably mouthed "G'morning;" I rarely vocalize that kind of acknowledgment, just because I figure they'd never hear anyway, and if they did, I'd be hollering loud enough to wake the dead.
Just as I passed him, he shouted out at me, "Good morning," in a really snotty voice, meaning to say that I hadn't acknowledged him and that it was because I was a snob.
He'd taken one look at the way I was dressed, and was so wrapped up in his perception that I wasn't going to acknowledge him, that he didn't even notice that I had.
(I shouted back over my shoulder, "I said 'Good Morning,'" in that voice loud enough to wake the dead.
