Proprietors should be allowed to determine whether or not you are allowed to smoke in their establishment. Then people could make up their own minds about whether or not they choose to go to that establishment. Employees could choose whether or not they want to work at that establishment. It's called freedom of choice and personal responsibility. Core American values, last time I checked.
You guys are all like "Fuck The Man...except when it's convenient for me." What bullshit.
