There are absolutely no concrete reports on toxic levels on people clothes harming anyone. If you are allergic yes, but I am allergic to perfumes and I don't see them saying people can't were it in close quarters.
Do you realize how many people do crap every day that endangers others lives? Hundreds. Bad drivers, drive by shooters, drunk drivers.
There is more of a chance of you getting killed by one of those on the drive home from somewhere. Than from second or third hand smoke.
Appa, you did the right thing, the other person was very rude. And I get sick of rude non smokers. The reason we moved is the guy was polite about it. He was lucky he was. Because my husband (AKA The Junkyard Dog) would have had some choice two words for him had he not been.
