here in Alberta there is no such thing as an included school lunch. Students either pack their lunch, go home or if their particular school has a cafeteria
I'm just going to jump on this point here, granted, my experience with the US public schools is limited, because our children only attended for high school.
When I was in school, and to the best of my knowledge, it would be ongoing, I can't imagine why it would be changed, kids were allowed to leave the school and walk home for lunch (or in the case of high school, go wherever they wanted for lunch...eat out or whatever). Large numbers of us (high school) would walk to the nearby mall, get something to eat at the kiosk there, wander around a bit, then make our way back to school an hour later. Kids that lived close to the school pretty much always went home for lunch. Since I was a "country kid" going to school in the city (20 miles away), I obviously couldn't go home for lunch. Plenty of kids took their lunches to school. Elementary kids ate in their classrooms at their desks and in high school, we had a designated lunchroom area of tables and benches, but if you wanted to eat outside or while you were walking to a store or whatever, you could. No food, other than vending machine chips, pop, chocolate bars was available. (So no lunch lady or lunch line with credits, etc.)
This is very much in contrast to how things were when my kids entered public high school here in the US. There was a designated lunch room/cafeteria and you could pay for lunch service or bring your own bagged lunch.
No kids were allowed to leave the school and the lunch break was SHORT. Where we had an hour off, my kids maybe had 20 minutes to get and eat their lunches. It would be impossible to walk home to eat. Both kids tried the school's lunch program, but hated it and ended up just taking their lunches every day for four years. I know someone who is a "lunch lady" at our local school and the meals sound horrible. When I think of images in my head of what school meals were like, I picture large trays of "home-made" pizza (the rectangle kind), meatloaf and potatoes, etc. She told me that none of the meals are made like that anymore. Everything is just dumped on a tray for "heat and eat."
