I'm in favour of keeping masks as a thing for a while but I wonder if it will become the next 'hand sanitiser', ie. something you get people to do to make it look like you're actually taking measures to reduce risk, while you just ignore a whole bunch of other stuff that would probably make a bigger difference.
For the first time in ages this weekend I went for a meal 'out' but sitting indoors. Something I am still planning to avoid as much as possible for a while. The place had hand sanitizer at the door, it had the NHS check in QR, the staff all had masks on. But then we were shown to a table in quite a large room, there was only one other table occupied but they put us at a table virtually next to them instead of one of the free ones at the other end of the room. It was a warm summer evening but exactly zero windows were open, and nor were the the full height patio doors. You had to put a mask on to go to the toilet though so it was all perfectly risk free.
