Kanye West is raging and ranting -- when he's on Twitter -- but in the real world the guy's acting like he's on a campaign to win a Nobel Peace Prize.
Kind Kanye's latest beneficiaries were a group of patient fans waiting for him outside his NYC pad ... and even the paparazzi who hung out for him.
Check out the vid -- at first he looks like he's gonna blow off everyone, not saying a word. And then he drops a very huge ... very valuable surprise for the fans. He wasn't done there. When he and Kim Kardashian return from dinner, you gotta see his chat with the photogs.
