There are, unfortunately the businesses, etc. who place them usually make it so that non-smokers have to walk through all of the smoking area. The worst case I saw of this was when I went to my oxygen company to get new equipment. The same building had a huge telemarketing firm in it. The only place those employees were allowed to smoke was at the front entrance. They took breaks in droves and they all smoked. It seemed strangely absurd and not a little surreal to walk through them with my O2 on. They were belligerent and rude.

Not all people who try to be sensitive/ethically correct follow the "PC" thing blindly. We do think for ourselves; we just prefer treating others kindly if we can, and yes, that includes smokers up to the point their smoke invades my space or that of my grandkids!*bg*
