Absolutely crazy. Here in England it is a joy to walk in the Spring Sunshine and go around the shops without a mask.
You will be one of the people I want to speak to whom I encounter in a supermarket maskless! (But I zip it!).
Of course we don't need to wear masks in the open air (unless we are within inches of someones face!) - and I wish we had some spring sunshine here in SW England - has been in very short supply recently.
Why though would people not wear a mask in a supermarket if this is advised? It surely is only polite and considerate to do so - to help protect other people as well as giving yourself some protection against the droplets that fall around you as people cough and talk (loudly sometimes). What I find most irritating is that it is some of the younger age groups ( mums and toddlers) who are not wearing them and yet it is this age group that I gather has the highest rate of infection and so may well be spreading it.
The disease may well be milder, but I certainly don't want it and we still need to try to keep infections down (impossible in England) to minimise new variants appearing which could be much more serious.
To me, wearing a mask in a supermarket ( or a cinema and theatre, or publlic transport) is still a small price to pay for trying to keep us all that much safer....
