I would be willing to bet anyone that eats at places with salad bars, raw lettuce (Tacos, etc), and other raw food stuff have eaten more than a tiny bit of poop in their lifetimes. That is why I am an advocate of Hep A vaccinations for everyone and as early as possible.
Sometimes you just don't want to think about things like fecal-oral route when you are out with the little woman having a (reasonably) nice dinner.
At least with a pill, you know it is (probably) disease free, what it is and why you are taking it.
