    Completely useless. Tried to mail a package to our son in Korea but the postal worker didn’t know how to mail a package to an Army Post Office and there’s never a supervisor to help. In addition the majority of our packages that are delivered to our mailbox are crushed or opened and taped back up. I have no idea why we still have a Postal Service, mail delivery needs to be privatized instead of having useless individuals pretending to be a serious organization.

    I pay for amazon prime to get two day delivery. Amazon does their part it gets to my post office in two days...but then it just sits there. Packages are late WAY TOO OFTEN. I call and they say oh they took a small vehicle and couldnt takr many packages???? We pay postage and taxes for this?? I have never experienced this with a post office anywhere I lived prior to this. Time to write a letter to Washington.
