If you keep reasoning down this path you eventually arrive at DishOps, where you dispose of dirty dishes by hurling them out of a window, and provision new dishes automatically on demand, by ordering them from Amazon for same day delivery as part of spinning up each meal. From a systems design point of view it approaches maximum theoretical efficiency, with no stocks of 'dirty' dishes accumulating anywhere, or scheduling conflicts over when to run cleaning cycles; the same approach also scales up from a single snack to a multi-course banquet for several visiting diplomatic entourages.
