Cher tried helping out her local Post Offices — but it sounds like not even the Goddess of Pop could penetrate good old-fashioned bureaucratic hiring practices.

The singer tweeted Wednesday she recently tried offering her services to a couple Post Offices in Malibu — as in volunteering, ya know .. since the agency’s strapped for cash, manpower and support these days under Trump’s administration. Sadly, she was rebuffed.

Cher writes, “OK,Called 2 post offices In Malibu. They were polite. I Said”Hi This Is Cher,& I Would like to know If you ever take Volunteers⁉️” She continues, “Lady Said She Didn’t Know & Gave Me # Of Supervisor. I Called & Said Hi This is Cher Do U Accept volunteers.”

She says the manager replied, “NO.” Apparently, they need fingerprints and a background check even for a volunteer. Makes sense, we suppose … can’t take any Joe off the street. Then again, this isn’t Joe … it’s Cher! And, she says she’s serious about helping out.

This is kinda where we’re at with the USPS these days — and it’s all because Trump has attempted to dismantle the service from the inside out … appointing one of his cronies to head it up, while dismantling mailboxes and sorting machines across the country.

Postmaster General Louis DeJoy just did an about-face, saying he’ll put a stop to any major changes to the Postal Service until after the election — in order to avoid the appearance of election tampering.

Good call. And, as far as Cher goes … getting her involved wouldn’t be such a bad idea either. She’s known for her philanthropy — just saying.
