The government announced last week that face masks will be compulsory in shops and on public transport from today (30 November), in response to a new Covid-19 variant being detected in the UK.
Retailers are required to communicate the rules for face coverings and have the right to refuse entry to customers who won’t wear a mask.
Independent Retail News suggests retailers put the poster up on their main door or front window so customers see it before they begin their shop.
The poster is free to download and print here.
