Boorish Baldwin’s a caf-fiend: barista

Starbucks would need more than a mere Venti cup to contain Alec Baldwin’s ego, according to one employee at the java joint.

Although the “30 Rock” actor complained on Twitter about his barista’s “attitude” following a visit to one of its Upper West Side stores, a co-worker insists Baldwin’s the one who blew his top.

“I was here when it happened — it was really just him being an [expletive],” a second barista told The Post. “He was very rude and disrespectful and arrogant. He’s probably the rudest guy I’ve ever met.”

Wednesday morning, Baldwin tweeted: “Starbucks on 93 and B’way. Uptight Queen barrista [sic] named JAY has an attitude problem.”

His name wasn’t Jay, but Giovan, the co-worker said.

“And he didn’t do anything wrong; it was all that dude just being psycho,” he said. “I saw a thing on ‘E’ a little while ago, and it was talking about how crazy he was. They were right.”

Giovan, who was off yesterday, could not be reached.

A Starbucks regular, Baldwin has no intention of curbing his grande habit on account of one employee, his spokesman said.

“Starbucks is a great company,” he said. “Unfortunately, not all of their employees can live up to their high standards.”

Following the incident, Baldwin reached out to the company’s corporate offices and spoke to regional manager Rick Coleman.

The chain did not return calls for comment.
