Per 911 regulations, all the rural mailboxes in our county are marked clearly with our numbers. A least once/week, every week, either we get someone else's mail, or someone else gets ours. I believe that enforced haste is the problem. All the companies promise unrealistic delivery times and then flog employees to make it happen. The inevitable result is sloppiness. It is exacerbated by employees who don't care.
Disclaimer: i worked for UPS, once upon a time, and it was a nightmare of goals, deadlines, and union red tape.
