And well returning to the subject he is freaking Justin Bieber that's why fans are paying all that, and it's better to be real and not faking a smile if he doesn't want to, at the end they met him and got a picture!
So you're telling me that he never smiles with fans ever? You're telling me that you can't find a single picture of him smiling. Try not to be so biased maybe.
He enjoys getting arrested more then taking pictures with fans.
