AH.74 I don't really understand your point about the smoking part in a gun store... You are not going there to eat or order food so what would it matter if the guy that is selling you a gun smokes? As long as he isn't blowing smoke in your face I cant see anything wrong.
Did you stop going to the bars cause people smoke there? Do you stop going to restaurants because they smoked in there? (the costumers that smoked)
