It’s the same here at the moment @
hvert mandatory masks on public transport and stores everywhere else anything goes. I do think bars and restaurants are higher risk than stores, people are there longer and face to face, often very close.
I think I the reason behind it isn’t exactly science but economics- hospitality can’t really function or thrive with masks and less people in. Stores are essential, they have to keep open whatever happens - supermarkets didn’t get the government support like hospitality had to. So if they make it difficult for hospitality they’ll need to give government support again - and they really don’t want to do that.
