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!
Lolz.. that is not a flush but a subsitute for the lota...lol... you will find that sort of toilet everywhere in middle east.
