This Post Office is either seriously understaffed or a few of employees there really hate their jobs. The guy behind the counter where you pick up your boxes has a serious attitude problem. If he really doesn't like his job he should just quit and do something else.
I stood in the long line to pick up my mailbox key and to also check on a box that was showed as delivered on the USPS website. All my mail was being held at the post office until I got my key, which I picked up. The box was not there. The guy told me "Go check your mailbox because it's not here!" Give me a break. How is a large box going to fit into my small mailbox? In addition their website showed it already being delivered! Totally messed up.
