Can I just say...
I am in a position to speak on this topic as I run a shisha business.. very prominant one. Luckily the ban didn't affect our business too much... but we lost much of our trade orders.
Anyway, more to the point; the ban is an absolute joke! It's absurd to think that the government can just take the british peoples freedom away under their noses, coupled with shitty traffic laws, and everything else; this country is rapidly becoming uninhabitable. Now I'm NOT a smoker before you ask...
Would you regularly visit a pub if you do not drink? THE ANSWER IS NO! So why the F--- should people visit a shisha bar if they do not smoke? It's called a SHISHA BAR for a reason. There is absolutely no grounding for enforcing this law at all. How will the second hand smoke effect any average person? They're all there to smoke, kill themselves, whatever.... thats upto them, it has NOTHING to do with the government. This really does need reviewing as I personally know peoples livelyhood has been taken away from them and there businesses.
If you ask me, this is more then just a ban, I think there is something more sinister going on...
