An email circulated in the government department where I work says 'smoking is not permitted in all areas of the building occupied or controlled by the Department'. I think the intended meaning is that you mustn't smoke in any of those areas. Am I being pedantic if I object that you could quite accurately interpret that as meaning just that there's at least one area where smoking isn't permitted? If I said, for example, 'telephones are not installed in all offices', surely you wouldn't think I meant that none of the offices had a phone? And isn't that a parallel example? Howard
