Watching people at a salad bar can be pretty disturbing. I love salad bars because they are usually healthy and I can serve myself and pick out what food I want... This is probably too strict for restaurants but it would be awesome if every customer who used the salad bar had to put a mask over their mouth while serving themselves... even using gloves would make it much safer/cleaner. Yes it would feel ackward and different at first but I believe everyone would feel the salad bar area was clean.
