It would be interesting to learn what percentage of transmissions shops (essential or not) are responsible for. I imagine it's pretty small. This seems one of the increasingly bizarre measures that spew forth almost daily. There four different lots of them at it and they are really making their mark - but possibly not in the way they imagine.
I wonder how far this will go? Many of the food items on offer in "essential" shops are not essential. You don't actually need doughnuts, lemonade, bottled water, cakes biscuits, and that's before you even get on to beer, wines and spirits. Are these shops going to have to split all their stock into "essential" and "non-essential"? Even in the darkest days of the first lockdown it was deemed lawful for shops which were allowed to open to sell "non-essential" goods (as Derbyshire Constabulary found out when they began checking the contents of shopper's shopping bags). If you're in the shop, you're in the shop and it scarcely makes much difference whether you pick up a tin of baked beans (which, strictly speaking, you could do without) or a new pair of socks. But it will make a difference when staff have to start arguing the toss with staff and management over what they can buy and what they can't. I think some of the thinking (if that's what it is) that is behind these schemes is bordering on a form of mental illness and urgent treatment is required for those involved. Unfortunately they won't receive it because they have not contracted Covid.
