I can remember similar from public elementary school in the early 80s in the suburban SF Bay Area.
In kindergarten, we had a rotating chore to take the collective milk money for the class, exchange it for a crate of milk at the cafeteria, and return it to the kindergarten room. I can imagine social norms have changed since then about this de facto mandatory financial exercise.
In later grades, we had some rotating lunch duties including, at least, rinsing the lunch trays and loading the big dishwasher. I can't remember if we ever helped serve food, but I do remember being told to be careful with the very hot water spray nozzle in the washing basin. I can imagine this having changed due to shifting safety and liability norms.
