Unfortunately I hear them quite often. I'm not a person who can stand hearing anyone making those remarks about anyone else. If I overhear someone making either type of remark, I'll tell them to "knock it off" (that's being nice for hubpages). Those people might not stop doing it, but they won't do it in front of me again because they know I'll report them. Some people might think that's a little much to report people, but sometimes it's the only way to make the workplace a better working environment.
