WHY??
Don't you realise the same air comes out, and you might as well not bother.
Just been shopping and the amount of masks under noses is unbelievable. I just don't get it!? If I see someone with no mask at all I assume they can't wear one for some reason. But under the nose?? I'm desperate to just ask someone but don't want to risk getting punched in the face 😬
Can anyone shed some light on this? Do they not know that it's the same air coming out as their mouth air?
