Here in Germany (Bavaria, to be precise) supermarkets had to get “bouncers” to make sure each shopper had a cart, wore a mask and so on before entering. No carts left? That means capacity is reached. There with your spouse? You both need a cart, because that’s how capacity is maintained. If you don’t like it, well, tough. The supermarket isn’t going to risk a hefty fine because you feel inconvenienced.
Which is a far, far cry from what my parents tell me is going on in Texas.
