It really bothers me to find a hair, even if it is my own. I worked in the business and took food safety courses. (We had to buy our own). I was told that there has never been a disease linked to ingesting hair. Ick. It didn't make me feel any better when I found a hair in my pizza once. I have seen a lot of gross stuff in my day. Maybe we should tell the managers when we eat somewhere when people are not wearing hair nets, that we would appreciate it if the workers would wear them. Those little paper hats don't do anything to keep hair out of the food. I am with you, hair nets please.
