The problem is the scumbag employees who don't wash their hand often enough, and thoroughly enough. If you thought about it/investigated it too much, you'd never go out to eat every again.
There was just a thing on the news the other night about drinking glasses in hotel rooms. Yeah, don't ever drink out of them. Although there are rules that they must be replaced every day, they're usually not. Sometimes they're just wiped off with a dirty towel, or cleaned with window cleaner.
