Officials in Greece have ordered people to wear masks indoors in more public spaces in a bid to halt the spread of coronavirus.
Holidaymakers must now wear them inside retail shops, offices, banks, food stores, hair salons and bakeries.
It was already compulsory at supermarkets and on public transport, as well as lifts, taxis and for staff serving customers at restaurants, cafes and bars.
Churches are excluded for the time being.
The Foreign and Commonwealth Office has issued an update for Britons advising them of the sudden rule change
“From 29 July 2020, it is obligatory to wear a face mask in supermarkets, cafes, banks, government offices, retail outlets, barbershops, hairdressers and related establishments,” it warns.
Both residents and visitors found to be breaking the new rule will face fines of €150 (£135).

It comes as the country recorded a small flare-up of COVID-19 infections in the second half of this month, the Deputy Civil Protection Minister said on July 28.
Greece's health minister said last week the country was not facing a second wave of infections but needs to remain vigilant.
Deputy Civil Protection and Crisis Management Minister Nikos Hardalias said: “The rise in infections in Athens and Thessaloniki proves the virus is still here.
"The requirement is for the collective good. The situation must not cause panic but neither complacency.”
The country has been praised for its control of the pandemic after officials imposed an early lockdown.
Currently, there are 2,702 active cases and 203 deaths up to Monday after imposing an early lockdown.
"We must not let any room for things to go wrong," Hardalias added.
