This is my big worry. I’ve seen a few other posts on here like this. We seem - in some places at least - to be rushing back to normality.
I’ve done two jazz gigs recently - the band has a nice little residency - however we have to be tested prior to going in, which means arriving thirty minutes early, we have to wear masks whilst walking about, and maintain social distancing. The number of people watching is limited. Basically everything to mitigate spread of infection.
A friend of mine held an event on Saturday. It was strictly tickets in advance only, and masks and social distancing had to be observed. Those were the venue rules, which seem sensible to me.
