In my own view, it is like making thing worst than ever before if there are ban on those area.
Why? No rest place for smokers to smoke and so, they smoke while they are walking and so, those non-smokers will be getting more 2nd hand smoke while they walking. Don't tell me that non-smokers will go to coffee shop and pub to siam those smokers?
Therefore, ban smoking at those rest place (open air) is not that wise. It might cause more problem in the end. Hope they wouldn't ban else non-smokers will be suffering more.
