The conference I was speaking at in Vienna was focused on Central and Eastern Europe, so the vast majority of attendees were from former Eastern Bloc nations (my nametag initially said I was from Romania (?!?)). Anyway, I don't think I've ever seen so many people smoking in my life. You would walk out of the conference rooms and it was as if someone had turned on a fog machine as everyone tried to get through a pack or two during the break. Non-smokers deserve hazard pay just for mingling at a conference like that...
