As an aside...
We have a community mailbox. It has not received any maintenance in 20 years and it is battered and rusted.
To me, this is a statement on our nation. The government is letting these little things go you have to wonder about things we can not see...
(I have complained to the postmaster, no response)
Why not just fix it instead of complaining? https://about.usps.com/postal-bulletin/2012/pb22334/html/updt_001.htm "Purchase, installation, and maintenance of mail receptacles are the responsibility of the customer." ... "The Postal Service may elect, under certain conditions, to purchase, install, and maintain curb-mounted mail receptacles or cluster box units."
I would add to the above, if the Postal Service has no money (which is true) then it ought not be paying for mail receptacles.
Many (most?) of us maintain our own mailboxes. Why should you be any different?
Or are you talking a drop box to send something out?
Most of those have disappeared around here, other than in front of the post office.
That gives you the impression they are short of funding.
Which they laugh about sitting around in the hot tub at the quarterly seminar in some distant city drinking $100/bottle wine. (Upper management only, thankyouverymuch!)
It isn't that there isn't money, it is where and how it is spent.
