Uh, Alec, too much caffeine

Alec Baldwin was so steamed at his Starbucks barista Wednesday morning that he ranted about him on Twitter.

“Starbucks on 93 and B’way. Uptight Queen barrista [sic] named JAY has an attitude problem.,” he posted.

It’s unclear what prompted the 30 Rock actor’s Venti venting, but it seems that he was so enraged he got the culprit’s name wrong.

No Jays work at that branch, the manager told The Post.

“Maybe he means Giovan,” another employee said.

Not long after lambasting his barista, Baldwin went on to praise an employee at another neighborhood spot.

“Clyde, on the other hand, outside DINOSAUR BARBECUE @ W 125 n H River is MY MAN,” he tweeted. “Keeping the hickory ovens going, he is 2dayz Coolest NYer.”

“I saw him on his bike and told him, ‘Hey, I know you!’ said Clyde Greene, 32, of his encounter with the star.

“He cut me short, cracked a few jokes.

“He said, ‘Are you sure you work here?’”

Baldwin proceeded to ask a slew of questions about the barbecue joint, Greene said.
