The idea
The smoking ban should be repealed and the right to smoke or not in a pub should be at the landlord/ladies' discretion.
Why not introduce categories for pubs, for example
Cat. A , No smoking allowed on the premises.
Cat. B, Generally no smoking inside but a room is provided for smokers.
Cat. C, Smoking pub , but a no-smoking room is provided.
Cat. D. Smoking allowed throughout the pub.
Of course smoking should still be permitted in external areas.
Why is it important?
It allows people the right to choose.
