It's the question that many people have been asking as it has become mandatory - from Friday July 24 - to wear a face covering when in a shop in England.
Do I have to wear one? And can a shop worker refuse me entry if I don't?
The short answer is - yes you have to wear one and yes they can refuse you entry.
The Health Secretary Matt Hancock has gone as far as telling shop staff they can call in police if people refuse to comply.
Earlier this month, Mr Hancock formally announced to MPs in the House of Commons that anyone failing to comply with the order in England from July 24 could face a fine of up to £100.
Mr Hancock said shopkeepers “can refuse entry” to people not wearing coverings and said police enforcement would be the “last resort” after the Police Federation of England and Wales pressed the government on the issue.
Should an individual without an exemption refuse to wear a face covering, a shop can refuse them entry and can call the police if people refuse to comply.
“The police have formal enforcement powers and can issue a fine.”
Shop assistants are nervous about the change after months of lockdown and the risk of shoppers who've tired of the various rules becoming potentially verbally - or physically - abusive towards them.
And the Police Federation, which represents rank and file officers in England and Wales, has said it won't have the resources to chase after people who are refusing to wear face coverings in shops.
And JD Sports chief executive Peter Cowgill suggested his stores will offer face coverings to people with out but added that it was not for his staff to enforce the law.
“The guidance so far is that our store colleagues are not really to get involved and it’s a police matter to enforce rather than for them to get involved in any potential public disturbances,” he told the BBC.
Mr Cowgill also criticised the delay to introducing the measure, saying “it will have an impact on consumer confidence” as he blamed ministers for “inconsistencies and the indecisiveness”.
