You can look at my earlier answer to similar question. Nobody gets punished for not following the rules. We are not a police state. Parents participate in setting up the rules and conventions. If you dump chocolate in your kids food box every day then the employees will simply talk to you about why it is a bad idea. They are not going to stop you or take away the chocolate. This is also about consideration towards other parents and children. If one child has lots of candy in their food box you make the other kids envious and they start complaining to their parents about why they don't get candy. That is why it is good to have common guidelines on what kind of food parents should put in the lunch box of their kids.
