If this government actually got off it's arse and did a blanket ban on smoking sooner rather than later then everyone would benefit. Even smokers would benefit as they would actually enjoy the taste of their beer once their taste buds recovered. So the suggestion of boycotting smoking pubs at this time is like cutting off your nose to spite your face! Unfortunately playing live music means playing in pubs otherwise you just don't play. Some folk clubs don't allow it but many do so you can see the limitations if you're trying to take your music to a wider audience.
