Elk sausage

One of the franchise owners I work with gave me some elk sausage last year. Nancy and I really enjoyed cooking it right over the grill on a camp out. Food is a great thing and it's really underrated. But, I have a couple of questions. 1) How did the inventor of cottage cheese know when he was finished? And, 2) Why do waiters in restaurants wear gloves? What's in the food that they're afraid to come into contact with?
