A Manhattan garage attendant didn't know 50 Cent from a dollar - until one of the rapper's entourage allegedly punched him in the face in a dispute over a Range Rover.

Vincent Reyes thought the man screaming at him Tuesday morning at the midtown garage was just another irate customer. The man had come for his red Range Rover, but the valet parking ticket from the posh Rihga Royal Hotel he tossed at Reyes didn't match the ticket on the car.

Reyes wasn't going to give up the car without a valid ticket. "If I turned over the car, it was my responsibility," he said.

Norman Bell, one of 50 Cent's posse staying at the Rihga, didn't take kindly to this news. "You don't know who you're f-----g with!" Bell allegedly yelled. "You don't know who I am!"

Reyes didn't. "He was just yelling dumb stuff. I just ignored him," the Ecuadoran immigrant said.

That's when Bell punched Reyes in the face and body, according to cops. Reyes didn't fight back, and ran outside the W. 53rd St. garage to flag down help.

Bell ran back into the hotel. He was later arrested and charged with two counts of third-degree assault, misdemeanors. He was released on his own recognizance.

Reyes, who returned to work last night, said he hadn't slept well since the pummeling, and was considering getting a lawyer if his pains don't go away.

Bell's arrest came after 50 Cent wowed crowds at Madison Square Garden as part of the Anger Management tour.

Police hit 12 of his crew with weapons charges, and a member of the rapper's management was busted for allegedly shoving a cop.
