According to 'Them', people are throwing too much food away. I have the 'waste not want not' mentality, and use up food rather than chuck it out. Perhaps people don't have the time or the expertise to cook up leftovers in tasty ways? Just after the War, we had the Pig Man who came round in a little van for leftover scraps. Sell-by dates also convince folk they'll be poisoned if the stuff is more than a day old. I see supermarket trolleys positively groaning with heaps of food, and wonder how any family can possibly eat so much. I can honestly say that IF our local Council introduced these boxes, there would be hardly anything in ours!
Richard, be careful, you're getting very congenial in your old age!!! :D
