Historical Oddity: The First Non-Smoker's Section in a Public Area?

Karl Radek provides insight into the question in his memoirs on the famous sealed train car trip into Russia:-

There was a constant conflict between the smokers and the non-smokers about a certain location in the carriage. We could not smoke in the compartment, because of the little four-year-old Robert and because of Ilyich, who would not tolerate it. Hence the smokers tried to convert a room which normally served other purposes into a smokers’ lounge.

Hence outside this room there was a permanent crowd of bickering people. So Ilyich cut a piece of paper in two and distributed permits. For every three tickets of category A for the legitimate use of the premises there was one smoker’s ticket. This naturally evoked further discussions about the value of human needs, and we acutely regretted that comrade Bukharin was not with us, as a specialist in Böhm Bawerk’s theory about marginal utility.
