Smoking in Restaurants

　I think smoking should be banned in restaurants. First, smoking is trouble to adults and children so it should be banned in restaurants. Second, smoking is poisonous to other people so people should not smoke. Third, if smoking is not banned then smoking areas should be set up in restaurants. Fourth, children receive a bad influence from smoke. Finally, smokers are not only bad so restaurants should make efforts because smoking is not good for the body. For these reason, smoking should be banned in restaurants.
