What Chris Brown Did: Argued with a valet who refused to give him his car keys without getting paid $10
When He Did It: March 2013
Why It Was So Controversial: Seriously, Chris? You snapped on a parking attendant over 10 bucks?! Yup. He yelled, "Fuck $10, give me my keys. We gonna turn this whole spot up. I promise you." And (of course!) he did it while a TMZ cameraman was filming.
