A Japanese friend of mine visited an American middle school as part of a science class. He was invited to eat lunch with the students or go out with the staff. He chose (after not having ever been in an American school cafeteria) to sit with the students he had talked to as a matter of respect.

He sent me a picture of what he was served -- cold pizza slab with a cup of fruit. His comment was simply "How are you to learn when your soul hungers? Is this really how American schools prepare the minds of the youngest?" I responded with "Oh you're lucky, you got the fancy meal."

That a cheese slice between two slices of bread with some mayo would be served to a child as their only food of the day was spiritually disgusting to him in a way he did not have words for.
