A black student at a Texas college says she found a racial slur on her receipt from a campus restaurant, according to reports.

Chelsea Shaw took to social media Tuesday after she saw that a University of North Texas student union worker referred to her as the N-word instead of her name on a receipt at the Krispy Krunch Kitchen, college newspaper The North Texas Daily reported.

“I need answers…,” Shaw wrote in a tweet, which included an image of the receipt.

Within hours, the photo made the rounds on social media and the employee was fired.

“We found out that it was not the cashier, it was actually the cook who did it. The cook came out and apologized to the manager,” Bill McNeace, retail dining services executive director, told the newspaper. “The cook, though, his employment has been terminated. As soon as we found out, we let the person go.”

UNT president Neal Smatresk responded to Shaw in a tweet Tuesday calling the racist slur “unacceptable.”

“It is completely unacceptable and not who we are as a community,” Smatresk tweeted. “We acted immediately to identify the person responsible and that person has been terminated.”
