My Dear mr. Hammond people have worked down mines and in dangerous locations for centuries. There were no do gooders banning mines or paint factories. In fact no gave a shite. Nor does anyone wish to ban parking lots at pubs on account of cars being the cause of the most noxious pollutants. If you wish to avaid pollution from cigarettes..avaid cigarettes..that is what I do. Common sense os so uncommon. Let the poor buggers have a pint and a puff.
