"Having a no-smoking zone in a restaurant is like having a no-pissing zone in a swimming pool."

Exactly;
or more to the point, in case your comment is too subtle for the average smoker:
Having a smoking-allowed area in a restaurant is like having a p*ssing-allowed area in a swimming pool!

That statement is so old, it's time for an oil change:

Smoking in a restaurant is like peeing in a pool.

If you want to put up a sign saying "Peeing is permitted" over your own pool, why should anyone else care?

The air in restaurants is changed 35,000 times a year; the water in pools once, if that. Only an idiot could fail to see the difference.

Don't like it? Stay out of your neighbors pool. He built it, he invited you, that makes you his guest, not his master. Maybe you should put a pool in your own backyard. Nah, easier just to have some thug stick a gun in your neighbors face so he sees it your way.

Don't swim in private pools if you don't want to taste the piss that is allowed there.

Much more appropriate is establishing smoking only retraunts and banning non-smokers. That way the whining would be reduced and the facists can continue to enjoy their McDonald's or Burger King luxury meals while we enjoy our steak, caviar and fine cigars.
