Your opinion.
But you still haven't told me how a privately owned business operated on private property allowing smoking would be of any danger to you.
I have explained multiple times
It is a privately held public conveyance. If they want to operate in our society they must conform to our rules
Public safety is one of those rules
Even if all the people who enter know the policies of the business?
Sorry but if you have no intention of patronizing a business that allows smoking then you and anyone else who does not want to be subjected to smoke does not have to enter.
You make it sound like you are forced to enter any bar or restaurant that might allow smoking. You are not.
You may be already in there, starting to enjoy your meal, when some assclown walks in and lights up next to you.
Did you think of that? Nooooooo......
