A Very "SAD" Impression of Switzerland

We have never actually been IN the country of Switzerland, and believe it to be one of the most beautiful places on earth scenery-wise.  Alas, we were ONLY in the Zurich airport in 2004 changing planes (coming and going) to Colombo, Sri Lanka.  I have a very sad "memory" of that airport.  In the bathroom stall next to mine I heard a loud grunting sound from someone in the next stall, later.....a hypodermic needle fell to the floor and shortly after that - a HAND came to pick up same hypodermic needle.  I also noticed the light in that strange washroom - it was a "greenish" type (later, I would read that such lights are put in so heroin addicts can't see their veins).  Just imagine if that is one's ONLY view of Switzerland (and it may not have even been a Swiss person in the stall next to mine).  So sad.
