Icarus, a return to masks in public places was being debated in France only last week. As of last week masks were still required on aircraft in several European countries (Italy, Lithuania being two I know of). Maybe scrapped over the weekend - dunno…?
Plenty of places still recommend masks on public transport - and no, I am not going to cite those places - instead of relying on my implied ‘hearsay’ check it out yourself.
But ‘recommended’ only works well in less bogan cultures, where people have some respect for those around them and are sensitive to peer pressure. Recommended would be a dismal failure here - punch-ups on the trams and all that. Hence, I think we are on course for mandates again.
