I think we have reached a point to where the social image and economics of permitting smoking in a business is more powerful than any government smoking ban.
Thus, you could open a restaurant, airline, bar or grocery story that allowed smoking, but in all likelihood, that business would fail.
Which is reason #5. The market can handle it, therefore the government shouldn’t.
Have to agree, but I still miss them sooooo much! I went to a county fair somewhere in Mich. and didn’t see anyone light-up. Things have sure changed! The cost is outrageous!
