Wearing face cover in stores in England is mandatory on Friday unless you are exempt.
It follows legislative changes that require the wearing of a mask on public transport and in hospitals.
Those who do not abide by the law will be fined £ 100 – with similar but different rules in Scotland, Northern Ireland and Wales.
But the big supermarket chains have their own rules about what happens when people enter their stores without face cover.
Some police forces have said they will not enforce the new law, and some shops are following suit.
This is the newest of the major supermarket chains, according to BirminghamLive.
Tesco will also have face mask stands at entrances, so customers can take and open a package, put it on and pay for it at the checkout, but there is no enforcement policy.
Sainsbury’s will not ‘challenge’ customers in the aisles because they fear ‘they may have a reason not to wear a mask’.
Cooperative staff will not question those without masks, but adds, “It is the responsibility of all non-exempt customers to ensure they comply with the new legal requirements.”
Waitrose tweeted, “We will not refuse customers with exceptions in accordance with government guidelines.”
Lidl tweeted: “Wearing a face covering is the responsibility of the individual and should only be imposed by police and law enforcement officers.
“The government has determined that store personnel should not allow entry to customers who do not have face cover.”
Aldi said shoppers should wear masks, but customers should consider people with hidden disabilities.
In an email to customers, Aldi CEO Giles Hurley said: “Last week, the government announced that face-wraps will be mandatory in stores in England starting July 24, so you must wear a face-covering to enter one. of our stores from this date.
“Even as the country opens up again, I know that many are concerned about security and don’t want the steps we are taking to progress, meaning we are taking a step back in the fight against the virus.
“For those vulnerable customers, you can rest assured that the measures we have taken to provide you with secure access to affordable food, such as early opening hours Monday through Saturday, will continue and that our grocery packages for home delivery will continue always on sale, “he said.
Asda employees are expected to leave the police to the police. CEO Roger Burnley said, “I want to reassure all our customers – wherever you shop with us – that we will respect the guidelines.”
A spokesperson added, “We comply with all government guidelines and we welcome customers who wear face masks or not.
“Our colleagues all have the option to wear face masks supplied by us, and colleagues in clinical settings (pharmacy and optical) have been required to wear masks since the onset of the pandemic, according to government guidelines on clinical workers.”
