Not sure where you are from but in the US I had to wear a mask throughout my infusion in mid April. I don’t know any Dr office or hospital that you can go into (unless you are the President or VP apparently) without a mask. Now many stores are requiring them.
At the same time we have the republican die-hards saying that they reduce your immunity and aren’t healthy to wear…sad state of affairs in the US. Basically I don’t go into an environment that doesn’t require masks. If they see customer avoid them the policy may change…or the customer base will change just to serve the population that is anti-mask
