There is so much in the news about panic buying. My supermarket shopping has had to massively increase because I have 2 teens home who would normally pick breakfast up on the way to school and eat lunch at school. Often after school, we would stop by at somewhere like subway. So in the region of 12-15 extra meals for them a week are now needed at home that otherwise would have come from "commercial" stock. So now that we are isolated, this quantity of food has had to come from the supermarket. If many people are in this situation then the hit on the supermarkets is massive. How many office workers would have been picking up lunch from a sandwich shop. My dh did this every day. So another 5 meals need to be supplied from the supermarket.
I wonder if there is a lot of food unused and going off that needs redeploying.
