When out the other night, the waiter delivered our salads and I noticed his thumb touching one of the leaves of lettuce. I know that food is handled by cooks, waiters, and whomever before it makes it's way to the table of course, so why does this bug me? Am I the only one? I don't eat that piece of lettuce, but while I'm eating the salad, that's all I'm thinking about! (of course, it was a guy with a hairy thumb; if it was a cute waitress, I might have a different opinion!)
