smoking don't necessarily have to be banned
there are areas where smokers can smoke , so they don't have to ban it. some people that smoke should know that if you see other people standing around then they must have respect and go and smoke somewhere else. Non-smokers should also have a brain and think that if you see some one smoking then walk away or ask them if they can stand and smoke some where else. but in-hailing other peoples smoke can be irritating.
