CVS has issued an apology over a White store manager—dubbed by the internet as “Coupon Carl”—for calling the cops on a Black customer in Chicago who attempted to use a coupon that staff said was counterfeit.

Camilla Hudson, 53, posted a video of the incident on Facebook on Friday, of store manager Morry Matson on the phone with police after another store manager, who wasn’t identified, said that the coupon she was trying to use to buy her items were counterfeit and said that she might have created it by hand, according to Block Club Chicago.

“He was nasty, he was unprofessional, he was dismissive, he was accusatory,” Hudson told Block Club Chicago. “His entire tone and demeanor was offensive and problematic.”

Hudson told Book Club Chicago that she followed Matson around the store questioning him and was eventually told to leave before he called the police. She said she was “not yelling, I did not raise my voice, I did not use profanity” and asked that they call CVS’s corporate office to fix the situation.

She recorded Matson’s second call to police. A police report was not filed, but Chicago police officials confirmed to Book Club that the call was described as an “assault in progress.”

“[CVS] does not tolerate any practices that discriminate against any customer and we are committed to maintaining a welcoming and diverse environment in our stores . . . Profiling or any other type of discriminatory behavior is strictly prohibited,” the company said in a statement, according to Fortune.

According to Fortune, Matson was a delegate for then-candidate Donald Trump during the 2016 campaign. Chicago’s Board of Election Commissioners accused him of forging signatures on a ballot measure. He is running for alderman for Chicago’s 48th ward, per Fortune.

“As a woman, as a black woman, as a native Chicagoan, I’m just tired of it,” Hudson told Block Club Chicago. “I’m tired of it.”
