Article where a undercover investigation took place and found that all of the hotels tested did not clean the glasses in the room at all.

One of the comments from the story is about the ice machines at restaurants (think Wendy's or other places where employees stick their hands into them to get the ice):

Still...this story definitely makes me wonder just how often this sort of thing goes on. It then makes me wonder about the other things, such as ice makers and how often they are/are not cleaned. Some grade school student working with a Uni prof did a small study where they tested for bacteria in restaurant ice machines and for good measure tested their toilets. Guess which one had fewer microbes? I'll have a coke, hold the ice please.

Ew.
