I've been rather worried at the sight of quite a few people in supermarkets not wearing a mask. I know they're 'exempt' but surely they present a risk and should get someone else to obtain their food for them?
We were stopped at the door of a Tesco and challenged for being two people together, in spite of being well-masked. I explained that I have a heart condition and need my husband to lift things and push the trolley. He needs me to translate and direct the purchases as his English is a bit dodgy, so we were allowed in. But non-mask wearers are far more risky I would have thought?
