Earlier today I went over to my neighborhood post office to mail a letter. It was after 5:00 so I planned to get a stamp from a self-service machine, but I arrived to find that the machines were gone (!). A worker came out to the lobby so I asked him about it. "They were removed." That's it; no other explanation! I asked him for a stamp. "We're closed. We'll be open tomorrow." Wow, customer service is definitely priority #1 at the USPS.
