In time maybe. There are lots of people who have got out of the habit of going to pubs because they found the smoky atmosphere unpleasant. Especially former smokers. They won't all come back overnight.

But I suspect there may well be more of those than there are of regular smokers in pubs these days. I'm sure there are pubs where it's been different, but in most places they're a very small number.

Anyway it's a done deal now, and we'll see how it works out from Sunday on.
