    The worst USPS ever. They returned general delivery packages without waiting for no reason even though they should have kept them for at least additional week which they also confirmed in writing last week. Nevertheless when I drove 300mi for the sole purpose of picking these packages up, I was told they were returned. Beyond insane. USPS, you're liable for the damage you have caused with your mistakes and all extra expenses including shipping and travel.

    It was the end of the day and the line was into the lobby, almost out the door. The postal workers were doing a great job getting everyone through their transactions and packages out the door with speed and grace. The Mills team is crushing it.
