In other countries, a few years after the ban, here is how it sits:
The long pre-ban debates are nothing but a distant memory. Smoking rooms have been banned because staff have to enter them and they are put at risk. Out door patios which were roofed over and glassed in are being taken down by order of various municipal bylaw enforcers.
Many outdoor patios are now smoke free. In some places, smoking is allowed only in businesses where children are not.
Smokers are generally happy about it. Business is up and the premises are much cleaner. The sales of Ceiling Paint has probably dropped however.
The audience has changed at my club venues and I now see whole families taking up large tables. The room is more full because of it.
The only places where you still find problems are usually in small towns where the owner is putting up too much resistance (to please the customers) and is in fact feeding the flames.
All in all, it's over and most of us are happy with that.
I understand that nobody likes to be told what to do but in all sincerity, choose your battles. This one really isn't worth the hassle.
