On a average day, you would go in at a exact time, mine 8:15, case your mail. Flats, letters, then mark your packages. then load your own vehicle with the mail thats going out. Drive the exact route thats given, and deliver in order. Sometimes you have to get out and deliver packages or letters that needs a signature to the door. Weather and dogs seem to be the hurdle that needs overcome. When back at the office, you put everything away document whats not been delivered.
