That is because its real purpose is not to track the mail but to track the employees in an effort to eliminate jobs.....19 or so years in that rat infested toilet....The only mail that the USPS scans at every time it moves is Express Mail....
I once waited all day Sat for a package that was supposed to show up with signature required. I gave up at 5 PM and went to my box to get my regular mail. There was my package that was supposed to be signed for. :evil:
WHO SIGNED FOR IT??? My neighbor that was dead for 6 years.... WTF? :wack:
