The fact that correspondence is needed between a ministry (of Culture) and a local government body (Municipality of Athens) about who is responsible for drawing up a study to clean a fountain can only be attributed to the peculiarity of Greek politics.
The working hours wasted on bureaucratic recriminations would be enough to clean dozens of fountains. This is not the only example where unclear responsibility serves as an alibi for inaction. But local authorities are elected to govern and act, not to unionize.
