I totally understand the social implications. But in reality thats all it is, the worlds not gonna end if people cant socialize like they used to, especially if its only temporary. Yeah its gonna suck for a while, just like the whole mask thing sucks, but it definitely wont be forever. Pubs going out of business is a big concern, but there r plenty of ways to counter that. If not, than implications would be huge...for pub owners.
Whether or not they come up with any sort of treatment, eventually everyone will have either caught it and died, or caught it and not died, or there will be a vaccine. And until then its gonna suck.
Maybe it'll even suck enough for china to start putting some food quality standards into place, who knows, stranger thing have happened.
Edit: as long as the pub has fire insurance and someone in has a lighter they r gonna be ok :-)
