In my opinion, it is unfair to ban smoking in public places. I don’t like smoking. I think there should be “No smoking” on bus, airplane, taxi, train, and in movie theater, because there are many people. But many smokers do not obey. Many people do not notice “No smoking” signs, because I think many people smoke. Small people notice “No smoking” signs and yet still smoke. I think smoking is bad for the health. The smoking one’s cigarette is annoying to other people and very harmful, because I do not like cigarette. But I think cigarette decided place smoking.
