What a relief.
Sometimes when i'm lucky, a cleaning guy over there tells me which spot is going to get vacant imminently and i pay him 5 QR for the service.

But i guess with paid parking, everyone would be queing up to pay hence could cause another mess.

Some parking spaces in S'pore have a system of automatically identifying vacant spots and a board at the entrance displays the number of vacant spots.
Could that be useful here?
