Here in Spain non-smoking legislation is simply ignored. People smoke in hospitals (everywhere in hospitals I mean, not in the non-smoking areas), train stations, airports. That's one of the reasons why we don't often go to restaurants. You never know when next door a free man is going to exert his free right to freely smoke a 20-inch cigar.
And, yes, a lot of tourists consider this as "tolerance" and decide they can do the same.
I still remember those two tears running down my cheeks when visiting Stockholm:

-"Could we have a table in the non-smoking area, please?"
-"The whole restaurant is smoke-free, sir."

Health-FAscism? Civilization I'd say!
