Give it a couple years, the cities and their bars will adapt and accomodate smokers like they have in San Fran, Sydney and NYC. You almost don't notice the bans in these places I've been since even when you're outside smoking in the winter your usually under some massive heat fan with comfy chairs underneath (take that, ozone!). That or they just cut out a bit of the patio roof, wall it up and claim that's the same as being outside.
Heat fanned patios are getting popular in European countries too (not in the Netherlands, since smoking isn't banned in bars and the likes yet)
I think it was in Germany, somebody decided to "calculate" the annual CO2 output of these fanned patios and then demanded that the government would do something about it
