I would never rant about smokers smoking in a designated area. However, my sons have asthma and I would be (and will be) very upset if someone smokes in their presense in a line or something.
I also hate when people smoke at the doorway of a restaurant or office building. Thanks, I am so happy to walk right through your smoke!!!
I really wish that smoking restrictions would be increased to the point that future generations would never take up this offensive and unhealthy habit. I grew up with smoking in my house and I hope it never comes back to haunt me health-wise . . .
But people should be nice to each other, both in person and on the internet. Should, being the key word . . .
