Same here. Unfortunately, there are some vociferous posters who insist that their method of shopping is the only acceptable one and everyone else must change to fall in line.
That's not what I'm saying, and I couldn't give a monkey's how you shop normally provided your method doesn't impinge on me (so, for example, if children are taken to the supermarket they are properly controlled and not running amok[1]). However, supermarkets, under the advice of the Government, have asked us all to make special effort to shop a certain way to reduce the risk of COVID spread. Like the rest of the advice, we should all follow it for the greater good. Once the virus has gone, you can return to having a family party in the middle aisle of Aldi if you really must.
[1] Stick them on reins if you need to (why does nobody do that any more?). I got quite annoyed a while ago when, to give one example, a small child whose head height happened to be roughly the height of the bottom of a basket held in my hand was running around and ran into and banged his head on my basket[2], then the parent had the temerity to have a go at me for "not watching where I was going".
[2] Being tall I know well about the danger area of the "blind spot". It is very easy to bang your head on something that is *only just* below your head height, such as some doorways, because from a distance it appears you'll fit under it, and up close you don't see it.
