Note to self: Don't get on Chris Brown's bad side.

A valet in Studio City, Calif., learned that the hard way after the singer felt he was being overcharged after attending a charity event at PINZ bowling alley, reports.

The valet reportedly tried to charge him $10, although Brown apparently believed others had only charged $5. Brown demanded his car keys, but the valet wouldn't give them up without the money.

After Brown threatened to "Turn this whole thing on out," one of Brown's entourage stepped in and gave the valet the money.
