I was on a post a few weeks ago regarding this, the OP had something I had never heard of, but meant that although not vulnerable couldn't wear a mask.
Her worry was that other companies would start bringing this in, including transport, so she would be unable to get to work, doctors appointments etc.
It is starting to look like its happening
No exception does still exist.
They may well start asking for proof. I doubt they will.
But it definitely decreases the number of people trying it on.
Our co op type shop had limits. X number of people with masks and half that amount when 1 unmasked person. It was still done via the machine queue thing.
But done so cleverly you no longer could have groups of 6+ school children or the builders from the site over the road in groups (who would remove their dust masks to walk to shop!).
It was amazing how once they found themselves queuing outside in the winter they started to bring masks! It's not a large shop so plenty of room to have normal limits of numbers.
