Called @ 3:03PM Fri. 3/20/25 and Nobody Answers ??? Regular Carrier (Rudy) Appsrently NOT on Route as we Only Received (1) Piece of Mail Each Day [Thurs & Fri] How could we Not Get "Got it Local" Circular with All Food Ads ? Will these eventually Show Up Dumped Somewhere ..... Worse than dealing with MV - IRS - Social Security trying to Reach Someone !!! Maybe DOGE should Check USPS NEXT !!!!!!!!!!!!!!!!! Sad - Both my Father and Sister in Law {Past Employees} and a Son who Still Works for PO over 22 Years - and they All Felt - Not as it used to Be ........... - Sadder ...............................................................
