YES, smoking should be banned in pubs and restaurants (LET, January 3) but we shouldn't stop there.

While visiting Watford's Harlequin shopping centre recently I noticed they have a total no-smoking policy in the shopping areas, with a polite reminder over loudspeakers every half hour.

All the shoppers follow the no smoking ban. No doubt other towns and cities do this and maybe Blackburn will one day.
