How do you handle it when somebody doesn't have medical problems but just doesn't want to be around it?
Depends on the place and the situation.
I have never refused a polite request to extinguish my smoking materials, whether it was in a place where smoking was allowed or not.
On the other hand, if someone gets in my face about smoking somewhere that it's allowed, I might just tell them to go to he!!.
Wouldn't that depend on the circumstances?
