Actually, I think that's gotta be one of the hardest jobs out there; my mom used to do that when I was a kid, and it KILLS your body. I helped her a couple of times and it sucked.
On top of the normal rooms, you'd be shocked (or maybe not...) how many people absolutely trash their hotel rooms, and the maids need to clean that all up. Puke, trash, beer bottles, cig butts, everything. It's gross, it's hard, and they only make minimum wage with no benefits. Disgusting, when you consider how much the hotels charge for the rooms.
Sorry, but that one hit close to home.
