I signed up for that Julie, I think I had an account years ago but couldn't remember my username or password.
I also hate people going the wrong way down the one way system in the supermarket. We have arrows and blockades in place in the shops here too, but the amount of people I see ignoring it is so annoying. Most seem to follow the rules, but you do always get some who blatantly ignore it. It's usually old people and men I've found! The old people don't even stay 2m away either, it's like they don't realise there is a global pandemic!
I also tend to go shopping when it's quiet, if I see a big queue then I just drive to another shop or go home.
