I voted the last option because I hate people smoking around me and I think smoking is a stupid, disgusting, and often inconsiderate thing to do.
But I have to clarify that I don't think smokers are dumb or shallow or self-conscious, just unwise. And everyone's unwise in some areas.
And I don't particularly care if people I don't care about want to smoke somewhere where I can't smell the smoke. Ehh maybe I should've voted option 2. Too late.
