But nothing was in the mailbox and/or outdoor step. I called PO and talked to Evana. We went back and forth in total of 6 phone calls.

She just called me, did not give details but just stated that glasses will be delivered in an hour. I am sure she went above and beyond to help.locate this package and I want to say big thank you to her.

Dont have a problem with the employees themselves Original review: I've only been here once after a long time, and the biggest problem is the speed, they're too slow even when it's not so busy.

On the rare occasion there has been delays, but this is to be expected from time to time as things happen and we're all human. USPS is pretty reliable and should be supported. It's a shame that MAAGA wants to destroy the service so we can only use private carriers and pay more. Just like they want to do with SS. More middle men taking a cut of our money is not good for anyone.

I've…read moredefinitely put off sending packages before just because I don't feel like wrestling with this USPS location. There is always a line of at least three people waiting to be helped. They only ever have two clerks at a time when there are five or six desks. And the clerks that they have aren't extremely efficient. Sometimes they'll chat with customers or disappear into the back for a couple of minutes while helping someone (I'm sure whatever they're doing back there is related to the transaction, but they certainly aren't hurried). I've had kind clerks and rude clerks, but the manager of this location is my least favorite to deal with. He's always been short with me and doesn't like to answer questions. When I went to get my passport renewed, I was told that I needed to make an appointment. I found this kind of silly as all I needed to do was turn in some paperwork, but I complied. When I showed up for my appointment time, they were running behind by 30 minutes. There is also no separate room for the passport procedure, so they take you at the desk like everyone else. It can get confusing, as there is only one line for the passport customers and the mail customers. They really should rethink the logistics of their passport renewal process. Basically, the service is meh and don't come here when you're in a rush! They do have a package machine in the front lobby that's open 24 hours a day, which is pretty convenient.
