How come you can get drunk in the airport for hours but you can't have a cigarette in any of them or outside I want to know why

Because drinking only affects you but others have to deal with your smoke.

There is a smoking area in one of the concourses.

Yes you can is a smoking area there

Well we have to deal with the people that are drinking and they say a drink can clam your nerves well so does smoking if its good for one then the others should be able to clam there nerves as well
