I’m a letter carrier. Not all of us are bad. I have a great relationship with my customers. This was a failure of management also. If I missed one package my postmaster would be down my neck the next day. Certifieds also are tracked and accounted for. So pure laziness allowed this guy to get away with it.
Ragging on the USPS is a popular pastime here on FR, but I have always had excellent service. I’ve shipped hundreds of packages, never lost one, never had one damaged (knock on wood) except for a few sent to me that were poorly packed.
Once I had a letter carrier knock on my door in the pouring rain to tell me that a package had been left by another carrier at a side door that I rarely use. I rescued it in time with minimal damage. Now, THAT’s service!
Humans do make mistakes on occasion, and there are always a few bad apples in the barrel, but in general, the USPS does a great job.
The ones in my neck of the woods are great.
All the best!
