Covid Restrictions

[Si Tie]

I have booked to travel out later this week from the UK.   I realize the rules regarding COVID are different so have a few questions
as I don't want to get it wrong and offend anyone.
Do I have to wear a mask in a restaurant/supermarket/bar/walking in the street/ the beach/taxi/hire car on my own/ anywhere I've not thought of?
Thanks in advance
