While I mostly agree with yuk,a bit of advice, Tact is only noticed when it's missing.When you piss someone off, they stop listening.

Some places that allow smoking also have "smoke eaters" that seem to help, and, of course, an exhaust fan is even better.

Let's face it, smokers and non smokers will never mix no matter what. As someone said, "A smoking section in a restaurant is like a peeing section in a swimming pool".

No one has any right to try to stop someone from smoking, but, their right to blow smoke stops where my nose starts. I know some smokers, and, they are intelligent, considerate good folks. So, let's not tar them all with the same brush.
