that's the truth. Back when i was a casual carrier, there was this one HUD duplex with poorly marked boxes on the wall. I was new, so I put the mail in whatever box seemed right. of course it wasn't and the people called to complain. The solution? hold the mail until an actual apartment number was visible. Wouldn't you know it? actual numbers got put on with a sharpie after the 1st of the month came and went.
Our Post Office had to do something similar with a group of 4 CBU's (cluster boxes) at a trailer court. They were old, flimsy, half the doors were missing from people prying them off, the last straw came when one was hit by a car! For 6 months, we had tried to get the owner of the park to install new boxes. Finally, 1 week before the 1st of the month, we held the mail for all 60 addresses.
2 weeks later, new boxes were installed.

Whenever I subed on that route, I would deviate the route enough to deliver the "trailerhood" earlier in the morning, rather than mid-afternoon, before most of the residents "came to" (vs. "waking up").
