I don't see how munchery could possibly be throwing that much food away.
1 - ordering closes (closed?) at 2pm.
2 - I generally ordered Sunday night / Monday am for the coming week: 2 meals for 2 people each.
3 - with price increases over the last 18 months, they're pretty price comparable to delivery. I have a hard time believing there's no gains to having an industrial kitchen rather than a storefront, and from closing ordering at 2pm.
Also, Munchery charged $7/delivery, and I tipped $5. So they should have been breaking even at 3.6 deliveries/hour, assuming your $25/hr number...
