tell a usps worker they’re part of a federal agency and they will deny it. dont know how many times they say they’re private.
USPS worker is almost an oxymoron. Almost none of them are hard at work. I would call them Post Office employees.
If they are private they sure have a government work ethic and attitude. Department of Motor Vehicles, Post Office etc they all sit there with that “I could care less about you people waiting in line” attitude. They know you can't take your business elsewhere. They know they can't be fired no matter how bad they screw up.
