It’s been pointed out to me recently that although the pubs in Britain smell a lot less smoky after the introduction of the smoking ban, they now smell much more of the other people in the pub, and that’s not obviously an improvement.
Unintended consequences work both ways, of course.
I’m told by a friend who writes about food and drink for a local paper that the landlords around his way are increasingly enthusiastic about the ban. If you have any kind of outdoor area, however scrubby, it’s now packed however cold it gets, freeing up a proportionate amount of space inside. It’s as if the government built them all extensions.
