Thank you! That's the answer I was hoping for :) I was just playing the devil's advocate about the whole "fan being nice" thing - dude is a major idiot. But yea, adults or not, someone should've stepped in - such is life.
The entire night I kept wondering what that guy's final tab was. I had 2 Blue Moons, a shot of Jameson and a diet Coke for my friend and my bill was 32 dollars. Every other song, up came the guy with a waiter tray with 5 shots of who knows what. During their last song Better Life, the guy poured the shot into Corey's mouth while he was playing the song. It was just out of control to say the least.
