Having had a conversation with security in local super market today. Apparently they are not allowed to ask people to wear masks or put them on properly. The reason given is you can not enquire about anyone's health condition. (Thus can not discern if they are exempt.) IMHO the country has to decide if just allow the virus to run or get real simplify and enforce. As is, their will be no controlling the virus.
I think I’m in the make guidelines into rules and enforce them, with discretion and relevant exemptions until a vaccine is developed, safe and the uptake of it is sufficient.
Then we get onto the whole anti-Vaxers issue.
