Mail Chair
Looking at this, it kind of looks like a little chair that someone put inside the mailbox, probably for birds. It looks like someone was trying to convert this mailbox into a birdhouse. It’s not the worst idea we’ve heard. It may not even be a chair; it may be a drinking or eating bowl for birds.

Well, as it turns out, all of our guesses are wrong. As a kind Reddit user explained, this is not meant for birds, and we have the internet to thank for revealing the true purpose of this strange mailbox. That tiny dish is actually meant for whoever is receiving the mail to leave some change for the postal worker.
