#In Spain, it's forbidden to bring your own lunch to school, whether it's a public or private school. In high school (between 7th grade and 10th grade), if you're caught somewhere else that is not the canteen during lunch hour and you're eating a home-made meal, you'll have a disciplinary process and you can risk yourself to be expelled from school. You have to choose between eating at home or eating whatever school has to give you.
