The smoke still enters the non-smoking areas. It's nasty the world is having enough problems as it is why make it worse. For those of us who have allergies, it's almost unbearable. Or at least have an enclosed area for smokers. Those wall dividers are not enough.
Smoke floats across the restaurant into non-smoking areas.
If you don't smoke, there is a very bad taste to your food while eating. Very disturbing to other diners. As long as bars are not included, I would like to see the ban on smoking in restaurants right away. Second hand smoke is very harmful to as asthmatic and it does travel indoors. The second hand smoke they create is cancerous is deadly to a person trying to live a healthy life style.
