Empty shelves do indeed look really grim. I wonder if the panic buying is spread by Facebook meme waves with a rolling menu of doomsday must-haves. It started with toilet paper, then tissues. Then pasta, rice, tins of soup, baked beans and spaghetti. Antibacterial soap, antibacterial cleaning wipes, antibacterial laundry liquid. Indeed anything with a label including a word prefixed by "anti". Then flour, but of course you can't do much with flour alone, so it spread to eggs and milk. But hang on: the eggs and milk will expire within a month. Shouldn't we be stockpiling chickens and cows?
