Maybe. But isn’t that just another form of social distancing, which is no longer required?
Same goes for masks. Of course people should be allowed to wear them if they want but it shouldn’t be a requirement.
Perfectly understandable if people would rather not attend but people who want to go shouldn’t be impacted.
It must be remembered that attendance is purely voluntary and supposed to be fun (I just about remember that). Even the staff will be attending crowded pubs, bars, clubs, sports stadiums, concerts, theatres and public transport etc. I think imposing restrictions is indefensible.
