While passing through the Frankfurt airport I noticed that no one was smoking and thought this was a Good Thing. That is, until I walked past a pair of small glass boxes, each about the size of a bus shelter, packed with people who were smoking. If you look closely at the pictures, you’ll see that the guy with the bright blue jacket is actually propping the door open but the cigarette smoke wasn’t pouring out. They must have been negatively pressurized because you really couldn’t smell the cigarette smoke, except from someone’s clothes when they walked by you as they exited.
I can’t imagine what it must have been like in there, but I’m certain that you probably didn’t need to be sucking on a lit cigarette to get your daily nicotine fix.
