So what is it with Dance/Hip Hop artists not liking money on stage?  This is Kid Cudi punching a fan for throwning a wallet on stage.  This was from a show in Vancouver over the weekend.  Someone threw a wallet on stage.  Kid Cudi returned it...but to the wrong guy.  That guy, knowing the wallet wasn't his....threw it back onstage.  Kid Cudi punched him in the face.  That last line is the confusing one for me. 

Remember when Pitbull punched the guy in the face for throwing money on stage?  These are hard times fella's.  What's with not wanting extra cash?
