Like every 10th thing correctly addressed and sent to my place - where I’ve been for 6-7 years - gets “returned to sender - no such address”. I think there’s one substitute postal worker who sees my apartment number and goes “3X… surely that’s fake”. (Not the real address but close).

For the most part I think postal workers are salt of the earth, - my granny was a letter carrier - but there’s also some real problems in the local PO.
