I was expecting urgent mail and rather than wait for delivery went to the post office to pick it up in the morning. However, the mailman had left with the days mail. The clerk gave me the mangers phone number to call. I called him and he retrieved my mail from the mail truck and personally delivered it at my address within minutes. How great was that!! Can’t thank them enough ! Great customer service guys.
