Now a related question: I know that the burger and fries part of a fast
food meal comes almost entirely pre-fab. The burger is weighed and
shaped off premises, frozen and delivered to the fast food place ready
to be broiled. The bread, ketchup, fries, are all made elsewhere so
portion control isn't a subject for the teenager that the consumer
meets. Even the potatoes for the fries are grown to specs so they'll
fry up the same all over the country with no adjustment needed for oil
temperature. To what extent is the salad made off premises and quality
controlled and portion controlled so it is the same all over? I should
think there'd be regional differences in lettuce and other vegetables.

I expect at least the ingredients come on the Big Truck along with the
burgers and fries. Just like supermarket bagged salads, only bigger
bags.
