I wonder how it's going to work in shops - I think they should keep 2m inside.
They could offer alternatives:
2m, queues and no face coverings; or
1m, probably no queues to get in but have to wear a face covering.
They can keep every other seat/row free in cinemas to start with.
I thought they were only going to open the outdoor parts of pubs first. But table-service only with a few tables taken out to allow some space probably works.
