Even worse, however, is that recently our own personal mail has been routinely returned to the sender for no reason. Packages, magazines and credit cards have gone missing or returned as undeliverable. There are two sets of numbers on our house, and the house is on an easily accessible street, so there's no excuse. We've been to the post office several times, but they don't seem to care.
I have to wonder if it has something to do with Obama's new postmaster general.
In my experience, it has been a lot longer than 18 months. I chalk it up to a disfunctional organization staffed and managed by union morons and government bureaucrats. Just my opinion, though.
Correction: 25% have gone missing. The others arrived--eventually.
