USPS Customer Service - ABSOLUTELY HORRIBLE!!!!!

The address for this incredibly disgusting post office is: 

HOLLIS, NY 11423-9997

They really do set the gold standard, don't they? And this is why I have very little to NO sympathy for post office employees when they complain about something. I may be generalizing but this is truly appalling.
