She says she dialed up Dominos on Friday, like she does at least a couple times a month, and ordered two pizzas for her nieces.
"When I got back home, my niece informed me what was on the receipt," Robinson said. "My appetite was gone. I was furious, I was upset."
The receipt had the N-word followed by "don't tip" printed on it. Robinson's 10-year-old niece, Brittany Shaw, was the one who spotted the racial slur - a word she knows of as being bad.
"All of the younger kids, we're not allowed to say that word," Shaw said.
Robinson says she grabbed the receipt and returned to Dominos to show it to the manager.
"He looked at the receipt, he was really nervous, upset, he couldn't believe it either," she said. "He was very nice too, he was very apologetic."
Charley Nordt, the general manager of the store, tells ABC11 Eyewitness News that they took the complaint very seriously and did some digging. Nordt says the delivery driver who put the racial slur on the receipt has been fired.
"For this to still be going on today, it's just not right," Robinson said.
Robinson says she is still angry and upset. She also says the person responsible for the message is not only racist, but ignorant.
"We just have to pray for people like that, just pray for them," Robinson said.
She says she hopes it's the last time she and her family experience something like that.
"I just want people to know that it's not right to do stuff like that," Robinson said. "It's not okay to be called the N-word."
The manager of the Dominos did say he believes it was an isolated incident, but they are still going through the system to make sure no other racial slurs exist.
