I never worked in one of these positions, but I respect the hell out of people who do. I did do a house cleaning job for a bit that was pretty bad and maybe that's where it's from, but I think I've always had that. I just respect people who do things for others, no matter what it is. I don't think it needs to be required, but maybe have a system to report people and enough reports forces you to do "community service" in one of these positions.
