Smoking outdoors

Sir, – Clive Williams (September 30th) claims that he has a "simple solution" to the problem of entrances to business, banking and government offices being polluted by smokers. My problem is that he never says what this solution could be. Presumably, he means that this activity should be banned.

Smoking outside workplace doors is in fact prohibited in many workplaces and in "smoke-free" hospital campuses, but enforcing that rule is well-nigh impossible unless bouncers are in situ to ensure that it is observed. – Yours, etc,
