The attacker said, “No! I gave you $3, so you have to give it to me!'" Goni told the television station.
Goni, who is the convenience store's night manager, told the man to leave the store, the Sun-Sentinel reported. However, the man went to the cooler, grabbed a bottle and threw it at Goni's head, cutting him above his right eye, according to police.
"He came and grabbed two bottles of beer and went again to the register, and (I) served another customer and he had two bottles in two hands and one bottle he threw at my face," Goni told WPLG.
The subject then fled the scene in a dark sedan, WSVN reported. The incident was caught on the store's surveillance camera, the television station reported.
