I was referring to a specific situation (a university campus) that already banned smoking from all indoor areas, and all outdoor areas within 100ft from buildings (could have been 200, I don't remember). The question was whether to ban it everywhere. That scene I used of the party was very accurate, you'd have about 1 in 20 people who smoked. You'd not bump into smokers in any other settings, basically. (You'd maybe see a random smoker smoking on their own far away from buildings.) This was early 2010s at a west coast university.
