I have no problems with people making their own choices as long as it does not impact my health.
Even assuming the second-hand smoke studies that show harm were true, a restaurant owner's choice to allow smoking in his establishment does not impact your health one iota. Your choice to go to that establishment would.
Unlike 2nd hand smoke, it is reality that some folks can actually die in reaction to peanuts or bee stings.
So far in Ky both peanut butter sandwiches and bee-keeping remain recklessly permitted.
Just so you know.
