No real surprises there.
I've always wondered why anyone lets their kids play with the toys at a medical clinic. Just think of the stew of germs on those things!
I usually take my Gameboy or DS and play that while I'm at the doctor's office. It takes two hands to play either of them so that helps me keep from unthinkingly touching anything. Plus they're small and convenient to carry.
I've seen a lot of people sticking utensils into stubborn bottles of catsup in restaurants, after they've eaten from the utensils. Squirt bottles should be less of a problem than the glass bottles though. I try to avoid the glass ones.
The ick factor is wonderful if you're trying to lose weight, because it helps you refrain from food samples of any kind. Until this last Christmas, our local grocery store put out their various bulk chocolate candies in open boxes. For years, the ick factor kept me from buying any, because I couldn't help but think about all the people who had sneezed and coughed over those open boxes. This year, they finally started putting plastic covers on the bulk boxes.
