The United States Postal Service provides reliable and affordable mail and package delivery. Reviews note significant differences between local offices. The Fairfax office has received criticism for rude and overbearing conduct from management, described as creating uncalled-for problems and embarrassing customers. In contrast, other experiences at the Fairfax office report very helpful service and a huge improvement, calling it the antithesis of the terribly hostile and incompetent San Anselmo office. For necessary services like passport renewal, customers report short waits and pleasant, helpful service at certain locations. The organization manages thousands of retail locations and is committed to processing and delivering mail worldwide.
