From an insider, let me tell you about the packages. I do it and haven't got paid exta. THe last one had a huge dog when I got there. We can't take a chance on getting dog bit.There is also a lot of paperwork involved on pickups. We are also on a time schedule and are always in a rush. Also if it will go in the box we put it in there. The postal service people have a lot of responsibility. Also on Fridays and Saturdays, lots of people get very little or no mail. Mondays is our worst day. Almost everybody gets mail. THe mail volume is two days mail on Mondays and if it is a holiday on Monday, there is three days mail on Tuesday.
