A considerable number of countries have applied laws for the ban of smoking in public places. Furthermore, the separate area for smokers and non-smokers customers in private places such as restaurants and bars, is a significant change that has caused positive or negative attitudes. The different views of customers and restaurant owners have created a legal and social debate. The findings suggest that on the one hand, the majority of the restaurant owners impose the law, but not actively. On the other hand, the non-smokers are in favour of the smoking ban and they have not reduced their visits in restaurants, whereas the smokers have reduced their visits and consumption to those restaurants that impose the law.
