Carmen Porter was assaulted by an unidentified man at Roberto’s Taco Shop in Las Vegas, which was caught on the restaurant's surveillance cameras (video below) in the early morning hours of Dec. 12.
Porter was going through the drive-thru when a male customer yelled insults at her.
"Do I just ignore it or do I confront him?" Porter recalled her train of thought to KNTV.
Porter says she parked her car, and walked up to the front door of the restaurant and confronted the man.
"I asked him, 'What did you just say to me?' and he began shouting and saying, 'It's called freedom of speech. You heard me,'" Porter recalled.
The surveillance video shows the man standing near the front door, speaking to Porter, which she said included racial slurs.
At one point, the man allegedly stepped into the restaurant, grabbed a "wet floor" sign and started swinging it outside the door, hitting Porter.
"That's when he went off and grabbed the caution sign, and started hitting me with it," Porter said. "My phone is covered in blood, and it didn't process in my mind: Get in the car."
The man reportedly walked inside, where he and a second man were ordering or collecting their food.
"To see him walking back to the counter to finish ordering his food, like it was completely OK," Porter added.
When the man and his friend left the restaurant with their order, the man allegedly grabbed the sign and hit Porter again outside.
"Just the derogatory terms that he was throwing at me with each whack makes me extremely angry," Porter stated.
Porter, who ended up getting 15 stitches on her forehead, said: "I'm probably going to have a scar for the rest of my life."
Metropolitan Police Department Lt. David Gordon told the Las Vegas Review-Journal that Porter is black and her alleged attacker is white.
According to Gordon, the attacker was with two other men, both in their 20s, and they departed the scene in a light-colored sedan. Gordon does not think the other men participated in the assault.
Police were still looking for the two men.
