Yes I've seen that too but those people had a choice to work there or not knowing full well that smoking was something they'd be dealing with. Nobody is forcing them that I am aware of.
Anyway, my take on this is ban the sale of cigarettes. Stop companies, the federal government and states from profitting on death. All tax payers need to stop the hypocrosy and buck up the lost tax revenue. It'll be billions but people will have a healthier smoke free environment. But that's not the push. The push is that we want people to smoke and pay all of that tax revenue but just not around me or any where I might wish to go. And now we are going to tell all privately owned businesses that they can no longer allow a legal product that every one of us benefits financially from in their establishment if they choose to do so.
I sound like I have a stake in this or something but I don't. I don't need to smoke when I go out to a restaurant with my wife and we don't frequent casinos or bars. I just feel that there should be places, if there's a market for it, that people can legally hang out and smoke if they wish to since it's legal to smoke.
