I was reading about those floods, nasty business.
Every few years the river parks flood here, but the city itself is protected and most people forget that it happens. The riverside shops and toilets are all designed to float or be towed away when it's expected.
Sad most don't think of consequences of their actions, very human thing to only satisfy oneself without further thought.
At lease your 'port-o-potties' float 😃, or steered away!
