I remember an airport in Venezuela
that had a whole row of "mirrors" that were mounted on a wall about
fifteen feet above the floor. Of course, it's quite possible that they
didn't care at all whether people thought they were mirrors; the
important thing was that you couldn't tell whether or not you were being
watched.

Post offices use these quite often. They are used by postal inspectors
looking for theft. The employees know what the mirrors are for but have
no way of knowing when inspectors are watching them.
