Ok overall there are 80% non smokers but the sorts of people that attend pubs etc tend to be more like 50% smokers. No pub is going to bar 50% of it's potential customers, therefore there would be no "non smoking" pubs, QED prior to the ban, there was nothing stopping a bar being non smoking but thet'd have been foolish to. Many non smokers tolerated it in the old days but now we have non smoking pubs, our clothes and hair do not reek and we are used to it there is no going back. "Dictatorial" is what we had up to the ban, ie non smokers where forced to endure or stay at home.
