In many schools, children do not eat. In the literal sense of these words. Cooks prepare, and kids do not appreciate this work and then just this food goes "to the trash." It is not right. Better to "Breakfast Buffet" made in schools. Then the students will be able to easily choose the food and to impose a portion of which he wants. But sometimes it is simply impossible, but it would be easier. Hopefully, someday any action will take. And then all will be well. And the food will not go away just like that, and students will be happy.
