While some might claim the worst Post Office in Brooklyn is in Park Slope... the Williamsburg USPS worker bees are working the hardest they've ever worked to steal that title away. The South 4th Street outlet is known for slow service and a blatant disregard for customer service... and sometimes technical difficulties! A reader tells us that those on line this past Saturday got the added treat of being told "there was a problem getting the computers started and there would be a delay for the windows."

One woman, in line right now, sends us the above photo and tells us there are no less than 33 people in front of her, and "only two people in the windows. People have been waiting for 45 minutes and longer! People are getting angry. Calling the USPS number to complain." As we go to press our disgruntled tipster updates us, saying, "Ugh. They just split the line. Now there is 1 person handling all the mail/ postage and 1 person doing package pick up. The line is shorter now but only because people got frustrated and left!" Hang in there.
