Tesco has revealed how it is trying to prevent people from shopping without a face mask.
In England, face coverings are mandatory in shops, with some exemptions for children or on medical grounds.
The regulation came into effect a month ago, on July 24, and anybody flouting the rule faces £100 fines - reduced to half that figure if paid within a fortnight.
But Tesco and the three other supermarket giants have previously said they would not make staff police the new law.
It did however say it would be creating signage to remind customers to wear coverings.
Now Tesco has announced a handy scheme for any customer who may arrive at its stores without a mask. Shoppers will be able to buy one at the entrance, The Mirror reports.
Tesco has also confirmed that some staff members may be spotted not wearing a mask due to medical reasons.
They responded to a customer who tweeted to ask why its staff were not wearing face coverings during a recent visit.
Tesco tweeted back: "Morning Ben, we’ve asked all our customer-facing colleagues to wear face coverings.
"There may be some colleagues, though, who are not wearing masks for medical or safety reasons. These reasons are set out by the Government."
