I was home today, and get to to the mailbox after seeing the USPS truck. In there, I find a "we're sorry we missed you" notice from that day. I ran after the USPS truck and eventually caught it.
The guy eventually admits that he never rang the bell or went to my door to check whether I was there to sign for his registered package. He just figured no one would be there on a weekday, put the notice in my mailbox, and drove off.
Good job USPS, way to go!|
