Once we were through security we were free to wander. As an antitheist it was interesting to see how devout people dress and behave. For some reason they think that dressing in a certain way, praying in a certain manner and reading teachings from thousands of years before will endear them to some omnipotent invisible entity.
The Jews do one thing, the Muslims something else and the Christians something different to both of the others. (No Hindus, Jains or Rastafarians that I could spot!)
Three different gods with different instructions maybe?
Just looks tribal to me!
