Slow Shipping USPS

The Post Office I use has usually 4-5 people standing behind the counter most days. There is usually only one service window open, the other is for incoming packages or pick up of packages. They 2-3 other people behind the counter are standing there doing nothing, I've been there as long an hour in line & witnessed this, I guess if you have enough rank in a civil service job you get to stand around & watch others work.
