What is it? I went into Sainsbury's and it's shop policy to remove for security to see your face. I did but asked them if they make people of religious persuasion take their head dresses off because they can't see their face. They said no because it infringes on their rights and helmets intimidate people. What's the law on this please? I've googled and cannot find much. I'm curious more than anything because it doesn't bother me removing it to make people feel better but when law is said I like to know who is right.
