Smoke Booth
Inject substance here
No, pictured in this mellow photo are no phone booths. What you see here, is the smokers corner in the Munich airport gate area (notice the "cigarette sign" on top?). Each nicotine addicted person is entitled to their own glass cage, probably well separated from each other, as not to raise any mistaken ideas of social behavior.
The cabins must have ventilation or some kind of vacuum cleaner sucking up the fumes. Still I noticed them from the cold smoke smell while walking by. No ventilation can be good enough. Good that I am a non-smoker.
