A confrontation at a Smoothie King in Ann Arbor, Michigan, has gone viral after a couple claimed employees refused to serve them because the husband was wearing a sweatshirt supporting President Donald Trump.

Cellphone video reviewed by USA TODAY shows the tense exchange between the couple and staff members, which quickly spread across social media this week.

“You literally looked at us and I asked you if everything was okay,” the woman says in the video. “You said, ‘We don’t feel comfortable serving you because of my husband’s hoodie.’ That is discrimination.”

The couple was later identified as Erika and Jake Lindemyer, according to reports from Fox News and the New York Post.

During the back-and-forth on video, one employee is heard pushing back, saying, “We have a right to refuse service here, and that’s what we did.”
