I dislike paranoia but I'm really getting leery of eating out. The food service world can't take too many more hits before they feel it. It's out of control.
You have reason to be concerned. I've been to too many restaurant restrooms and seen so many come out of the toilet and walk right out without even getting close to the sink. Surely, some of these slobs are involved in preparing and/or serving the food. I've begun to avoid eating out whenever possible since I know that there are lots of food-borne diseases. And it's a bigger problem now that we have more and more immigrants to whom hygiene is a "foreign" concept.
