A post office. Location - inner west.
The letter posting box out the front has been this way for weeks. It's not like this is out in the sticks with no Australia Post employees around. At least two of them walk in and out of that door 20 feet away several times per day - yet they fail to notice this. Or they notice it, and don't bother to report it.
On top of that, a contractor arrives once a day to empty this letter box. He parks right in front of it and sees it from this angle. He fails to see it, or report it.
Everyone thinks it is somebody else's problem.
