In the video Brown tells the man:
Give me my keys, f*ck 10 dollars, give me my keys! We're gonna turn this spot up, I promise you
Someone in Brown's entourage seems to hand over the ten bucks, Rihanna's on-again/off-again beau tells his crew:
Funky ass ten dollar!
And yes this is the same Chris Brown that is estimated to be worth $24 million.
