If the masses of medical experts that know more about medical science than any of us are all in agreement that masks help prevent the spread of Covid are not enough to convince you then you are beyond help and determined to be ignorant. You don't want evidence, you want a comforting fairy tale that tells you what you want to hear.

As for Shop Workers not wearing masks. Shop workers go to their shop and stay there for hours, if they go into other shops they were masks just like anyone else but the risk of infection comes from shoppers who might go to several different places in one trip. Not wearing a mask just shows that you think shop workers are lesser human beings not worth protecting.

Also a reusable fabric mask costs like £1-£2 in most places. Get into the habit of keeping a mask on you if you're going out.
