Airports are surreal places

I'm camping here in athens airport. what makes these flying 'bus stations' with borders surreal? Well the repetitive background muzak, numerous identical shops with 'cultural' gifts , millions of identical glass doors that are closed, hundreds of identical security personnel, repetitive, weirdly translated, and highly annoying public anouncements. Get the picture. But despite this alien zone people are surprisingly friendly .. friendly .. friendly ... ;)
