Rude Managers or Rude Fans?

A GIF of EXO-M's manager's slapping the fans. Who should we blame? The rude manager or rude fans? 

What I see from this one, the fangirl was only taking picture. Does taking a picture deserves a slap on the face?

And from here, the fanboy just wanted an autograph/handshake, does that deserve a slap in the hand?
