I had the opportunity to spend a couple of hours in the otherwise very nice airside center and was also surprised/shocked to find these smoking bars. And then all three of them ... it surely bothered me enough not to go there and get a snack/drink. I wonder whether all together they win more customers than they loose with this policy.
In fact, as the bars are open and not specially ventilated, the smoke of the bars is rather strong from quite far away. Very annoying indeed, and then there was this nice Camel-sponsored smoking room ... completely deserted!
