Craig Wayne Boyd may have just won "The Voice," but he wouldn't even be a finalist in "The Brain," because he almost immediately disrespected the fans who will determine his long-term success.
Boyd was leaving an NYC office Building Wednesday ... when he squeezed in an autograph and a mid-stride selfie, and then blazed past the other fans.
The little people know the game, and warned the singer he's starting off on the wrong foot.
"The Voice" is a really good show. Now name one of the past winners.
