This is something I have apparently been ignorant of my whole life.

When I was in school, only the "poor" kids ate hot lunches, unless it was pizza day, when everyone ate school lunch.  I almost always brought my lunch, and most of my peers did as well.  And it's not like we were wealthy or anything.  At the beginning of the month, your parents got a menu and ticked off the days their kids would be having school (hot) lunches.  So  kids would bring their lunches most days, except when the school was providing something you'd actually want to eat - which was rare.

I always felt sorry for the kids who had hot lunches everyday - because like your cheese sandwiches, you knew they were poor.  Even when I was like 7, I understood the whole "subsidized" concept.  It didn't help that they got to line up to go first to lunch.  I think it was in part to make them feel better, and in part because they had to go stand in line and wait while we could just plop down and open our lunch boxes.  But they were nevertheless separated out.  Having to wait was still better than being poor.

Lunch boxes.  Now, not ever having had a lunch box - that would be sad.  All kids should get lunch boxes!

I myself love cheese sandwiches.  I suspect the poor kids I went to school with have trauma related to hot school lunches.  Those hot lunches were seriously gross.  They made hospital meals look gourmet.  

Honestly - this is the first time I have ever heard of any kid not liking cheese sandwiches.  I had no idea!

High school was a different matter.  It was more food-court like.  I don't know how anyone kept track of who was getting fed.  Not to mention lunch was when kids snuck out to the parking lot to smoke.

Anyway, feed the kids already.
