Maybe you didnt notice, there are many more STRANGE and WEIRD things about that place (including the inhabitants), not just the airport toilets. Those other strange things make the weirdness of airport toilets looks insignificant.
Im glad that you returned with your own brain still in place. Do not risk re-visiting, though.
AIRPORT are STRANGE.
They are already filled to nearly the top with hot water b4 u use them,
They have a mind of their own and flush themselves without warning.
The flush is upside down, the water rises from the bottom (no pun intended!) up.
I don't understand them, i'm frightened of them!
