Apc; I have to disagree with your statement that the smoking ban was not a cause of many pub closures. Prior to the ban, there were 4 pubs within walking distance to one another near me. People visited these pubs on their way from work and of an evening. No-one ever wanted food served in these pubs - not that sort of clientele. 3 of those pubs are now shut, as is another just a couple of hundred yards away. Of course, high rents played their part but, imho, so too did the smoking ban.
