AIBU not to have let her in without a mask.

[Trialanderror02]

I know masks are a touchy subject and I am not against people who are exempt from masks. I don’t judge or shout at people in the supermarket 🤣
Today I had British gas turn up at the door for meter readings, she was a little rude when I wouldn’t let her in the house ( CEV house ) as she was not wearing a mask. She explained that she was exempt but right now we are in teir 2 no household mixing etc was I unreasonable not to let her in without a mask. She kept telling me she was exempt so therefore did not require to wear a mask
Which like I said I would usually accept but not when they are coming in to my house. I do not take DD ( CEV ) in to shops etc.

Many/most (virtually all?) those who have one of the suggested exemption conditions are perfectly capable of wearing some form of face covering. Your condition doesn't make you magically immune or act as a mask equivalent,
This , I know two people on the shielding list with severe asthma who wear masks one is a child. Another person has a blue inhaler only the same one for two years and claims they can’t wear a mask.
Mask exemption is like a dla claim it’s not the condition itself that’s relevant it’s how it affects you.
The amount of people genuinely exempt is tiny.

No, you weren't unreasonable at all. I have a heart condition so would probably be exempt, but I'm also a nurse who goes into people's homes. I wouldn't dream of not wearing a mask.
