I think that is the best thing. Anyone who is exempt is probably best having an exemption card (there is no requirement but it can make things easier, and avoid the need to say anything, if that makes people anxious) in their wallet, which they can produce if such a situation transpires.I’ve decided I’m not going to wear a sunflower band as of tomorrow. I’ll keep it with me but I see no reason to display it as I can’t be exempt from a mandate that doesn’t exist.
(Sorry if OT, I’m not sure if it’s a new thread worthy topic?)
I expect we will see between 25 and 50% (depending on if it's a local or longer distance service and perhaps time of day etc) not wearing masks initially, this will soon increase to over 50% within a matter of perhaps two or three weeks. Once the unmasked are in the majority, it will increase further until in just a month or two those who are masked will be very much in the minority.
