Smoking-only establishments

While I agree in general with the ban on smoking in public places, it is ludicrous that a publican or restauranteur cannot open a smokers-only establishment, staffed by smokers and catering only for people who want to smoke with their beer or meal.

Why does this idea matter?

It restores freedom of choice. And it enables catering establishments and public houses to recoup business they have lost because of the smoking ban. I will once again want to go out for a restaurant meal.
