White Milk 5 Cents, Chocolate 6

In elementary school for years, the milkman would slip into the classroom, read the order on the blackboard, then leave whatever small-carton-milks requested on the chalk ledge. Milk was then consumed by the kids at recess or lunch. His appearance would always happily distract kids, especially if a driver changed. An order was ratioed, typically, at approximately 24 chocolate, 5 white, and not everyone could afford school milk.
