Supermarket chain Sainsbury’s will enforce mask wearing and shopping alone in its stores.
The firm has written to customers to ask them to play their part in keeping everyone safe, and said it has “significantly reduced” the number of customers allowed into stores at any one time.
Simon Roberts, chief executive of Sainsbury’s, said: “I’ve spent a lot of time in our stores reviewing the latest situation over the last few days and on behalf of all my colleagues, I am asking our customers to help us keep everyone safe.
“The vast majority of customers are shopping safely, but I have also seen some customers trying to shop without a mask and shopping in larger family groups.
“Please help us to keep all our colleagues and customers safe by always wearing a mask and by shopping alone.
“Everyone’s care and consideration matters now more than ever.”
