Apparently, JD Whetherspoon shares fell, after the company issued a profits warning. The pub management firm is worried, that the smoking ban, to be introduced in Britain this summer, will reduce earnings in the short run.
I think it's probably a great opportunity to buy, since Whetherspoon's pubs are extremely popular and the ban will apply to all, so their pubs won't suffer more than others. And as long as no drinking ban is legislated in this country (chances of that are much lower than me winning all lotteries on the planet on the same week) people will go to pubs to drink a pint or two.
