If you saw an old moth-eaten sofa in an alley in the Bowery, would you lie down in it and take a nap? Sometimes I think staying in a hotel is just about equivalent to doing that. You don't know who slept in that bed before you got there. And the Hilton is just about the worst! Yuck!
I wonder how she discovered it wasn't scabies (takes weeks to realize you're infested with them)? Even 'clean' people can be infested with scabies before they realize they're there.
