Updated Thursday: Revised to include letter from UNT president.

A student-employee at the University of North Texas has been fired after another student was labeled the N-word in a receipt at a campus dining facility.

The woman, who said on Twitter that she wanted answers, on Tuesday posted a photo showing the racial slur in the space for an ID on her receipt for buffalo wings.

A cook at Krispy Krunchy Chicken in the student union admitted putting the slur on the receipt and has been terminated, university spokeswoman Leigh Anne Gullett said.

"Our Mean Green family values respect and prides itself on inclusion," UNT President Neal Smatresk said in a tweet. "It is completely unacceptable and not who we are as a community."

In a follow-up letter to students, Smatresk tried to clear up confusion on the racial undertones of the incident.

"It is important to know that both the customer and employee were the same race," he wrote, "and regardless of other societal views it is my belief that the use of this term is never OK."

The university is investigating whether the cook, a student, will face further disciplinary action, Gullett said.

"This one incident is so contrary to who we are, to the shared values of the community," she said. "I think that's clear in both what President Smatresk said and everything you see and hear when you're on our campus."

In tweets, the woman, identified by North Texas Daily as Chelsea Shaw, said that she was not asked for her name, as she usually is, when she went to the register and ordered.

She said on Twitter that she went to management before posting an image of the receipt, but "they said they didn't know."

Shaw, whose Twitter bio describes her as a UNT communications major and licensed cosmetologist, said she wants to speak with the university president directly.

Smatresk, who was out of town Tuesday as the situation unfolded, said he would be happy to meet with the student, Gullett said.

Shaw had not responded to a request for an interview Tuesday evening.
