The communications have been a **** up from start to finish. Due to incompetence and effective masks not available (and even if they were people can’t realistically tolerate them for every day tasks) the whole thing has been botched. The best bet in unpredictable circumstances would have been to say ‘face coverings’ are a simple control measure which intuitively makes sense so we’re making it mandatory. I suppose better late than never but it would be foolish to think this is the complete answer.
