Gotta love the morons who think it is possible to avoid wasting food completely. Reliability is only achieved through redundancy. If we only ever had just enough of everything, we would always be on the brink of a famine if something went wrong.
Reminds me of the local cafeteria at my uni that reduced food waste, so when I went there at 1PM to avoid the crowds (they served until 1:30PM) there was just no food left. Good job, so helpful.
