Yet they are enforcing them. In this video clip from Sainsbury, they escorted a lady out of the supermarket because she wasn't wearing a face mask. She even tried to educate them with a print out from the Government website clearly stating that a person who has a medical exemption need not wear a face mask and does not need proof - but they refused to read it. These are the stupid coppers enforcing the law on minimum wage with no training, reading skills or common sense whatsoever.
