Seems to me selling about to expire food to higher wealth individuals would be a bad business model. If they find out, the store goes out of business.
No it’s an excellent business model. For one thing most meats actually taste better the closer they get to expiration (curing, it’s your friend). And once you cook it you start a new clock, it’s no longer aging as uncooked meat, you just bought another week (handy to keep in mind at home too, I’ve cooked a few things straight to leftovers because they were getting old).
