Yeah, I entirely agree with you here.
Near the beginning of _Roger & Me_, Moore gets an easy laugh by his comparison of 'blue-collar' Flint and 'yuppie' San Francisco, by showing a waitress reciting a variety of coffee drinks--espresso, cappucino, cafe mocha, blah, blah. In that scene, the waitress--who is a worker, whether Moore likes it or not--gets somehow used as a butt of a joke, identified by Moore with yuppies she serves but not with autoworkers.

P.S. I think I far exceeded Doug's informal post limit, so I should shut up for today.
