Slight topic swerve...
Another thing i found, first in Eastern Europe although i've seen it elsewhere as well, is that light switches for smaller enclosed rooms without windows are usually placed OUTSIDE the room. Think one person bathroom in a restaurant, or even in a home. i've also seen it with closets and other rooms as well.
The first time i saw this all i could think of was 'why oh why do we put the switch on the INSIDE of the room?'. I mean think about it. How many times have you gone into a small public bathroom, let the door close behind you, and then had to fumble around like a blind man trying to find the stupid light switch?
One of the things i really enjoy about traveling outside of the U.S. is finding out how other places do things, especially things i've always taken for granted as always being done one way. Sometimes their way is silly and ours is clearly more efficient, but often their way is so obviously superior that you wonder how "the greatest country in the world" could not have seen to do it that way.
