I think we act the way we dress, on the job, traveling or anywhere else. People seem to act more civilized when they are dressed in some type of decent manner. That said if someone is paying for their own way it is not up to me to judge or control how they dress. As for the non revving situation. Recently my son was flying home from his grandmother's funeral. First Class out of Chicago. He had on a nice pair of slacks, Timberland shoes and a Tommy Hillfiger polo shirt (not tucked in) ORD gate agent handed him his boarding pass with the comment, "tuck in that shirt, you look like a slob". So I think they are still enforcing employee dress class. At one time employees had to dress up to not stand out from the paying passengers, now we follow the dress code and really stick out.
