I haven't been in one for a long while. There used to be signs asking motor cyclists to remove their helmets.
Do they want customers to remove masks, too?
I think the crash helmet signs are because robbers were using them to cover their faces, masks do not hide so much so should be ok, sure someone will correct me if I'm wrong.
douglas, banks and building societies do ask women in niqabs and burkas to show their face to a female member of staff. I have seen it happen several times.
sandyRoe, you can keep your mask on for the time being
