 Children in most districts cannot bring their own meals to school until they reach high school, nor do schools have vending machines; instead, children are taught to eat what they are served.In both elementary school and middle school, students put on white coats and caps and serve their classmates, who then all eat together in their classrooms instead of in a cafeteria.To make lunches affordable for students, municipalities pay for the labor costs, while parents, who are billed monthly, pay for the ingredients.
