There's a letter in todays Telegraph complaining about the smokers (and smoke) in the beer garden of a pub. The author doesn't seem to appreciate that the beer garden is full of smokers because they have been sent outside from the pub!
It's a case of "When we want to drink inside (in the winter) the smokers should be banned (sent outside). When we want to drink outside (in the summer) the drinkers should go somewhere else.

Even as a non-smoker I find the attitudes very confusing!
