Here in Ca. I believe it is law that food service workers must wear some kind of hair containment. I have owned two restraunts, and worked in several more, and ALWAYS had to wear some sort of protection. What is worse is the overuse of those awful vinyl gloves. I have seen some workers go from task to task without changing them. I was in a Sams Club one time and the girl at the cash register (nothing dirtier than money) had on gloves, and went from the register to serve my hot dog with the same gloves on. I asked for my money back and went elsewhere. Yucck
