I think it is better to just not think about it. I appreciate the new style of restaurant layout where we can see the kitchen and the people in it. The spots like Chipotle and Subway where they assemble the food right in front of you is even better.

I worked in a couple of fast-food pizza places and we never had anyone taint the food. There was no 3-second rule or any shenanigans like that either. I don't understand the mind of a person that gets some sort of enjoyment out of messing around with something that someone else is going to eat.
