Anyone who wasn't a brainlet could see him spazzing out in public coming a mile away, it doesn't take much to see a young naive idiot who previously got drunk on (minimal) power having a tardout the moment the mainstream attention they so crave comes around.
I would be surprised if he *only* throws sodas at people before his current mainstream attention fades out.
Edit : suggestion for Nick, carry a bag around, you're about to get a lot more 'fast food donations' coming your way, don't let the burgers go to waste.
