^^Right. Heck, the chicken-soup delivery in TiY was no more remarkable than a present-day coffee machine -- you push a button and a few seconds later you get a hot liquid delivered in a container. There's no reason the food slots couldn't have various flavors of soup, coffee, tea, and the like kept hot in vats just above the food slot, with clean dishes and utensils being stored nearby as well. It could be achieved with today's technology. No need to assume it had to be a replicator.
