Literally the WORST post office in America! The employees are profoundly unhelpful, refusing to look for packages available for pickup or give you packages that are at the post office waiting. They can take days just to deliver to a PO box, and it can be nearly impossible to pick up packages that have house addresses.
This post office should be AVOIDED LIKE THE PLAGUE!!! UPS, fedex, DHL, even CARRIER PIGEON IS BETTER!!!

As a PCT hiker, I’m more than satisfied with this post office. I sent myself a general delivery box — it arrived quickly. I picked it up in under a minute. The staff are friendly, kind, and happy to see hikers.

Most nasty, hateful, people on the planet work here. They give all postal employees a black eye. They had my hike resupply box (confirmed) when I arrived and refused to give it to me. If -0 stars were an option, that is what they would have received.
