I am arguing for designated pubs where smoking is allowed outside. I am positing that you could open a beer garden with smoking in the arctic and some happy cougher would turn up preachin' an' a wailin' :)
Man you really have a weird obsession with caughing. Whatever your emotional scars, I offer you a safe space to talk about it.
If pubs found a way to offer both, why not. A bar I go to a lot, has an outdoor area where you can smoke, and outdoor areas where you can't. It works well. The areas in which you can't have a canopy over them. The areas you can, don't. It is easy to tell them apart, people don't take the piss and stick to it. Very few actually choose to sit in the smoking bit. Even smokers. They would rather sit in the main bit, and walk over there for a smoke and come back. Wouldn't be against it at all. If they can't, then they default to no smoking on the premises at all.
