I see this as a Passive aggressive action. I actually a few days before Jack Straw even mentioned it was in my local supermarket, and used to women with headscarfs etc was offended by this woman looking at me through her "letterbox" I immediately thought that as Funkymoped says I know guys who pop into that shop who have to remove their helmets or I work with young people who wear hoodies who arn't allowed in with the hood up. I felt angered by it, because she probably would go home and tell a story of how I looked at her fuuny racism etc. But I am not racist, I thought she was rude. Because lots of people know me in the local shop, when it gets colder I might just wear my balaclava while I nip in. What would happen then?
