CHICAGO (CBS) — Some teen girls dining at a restaurant in a suburb south of Chicago say they were verbally abused Monday by another patron, apparently because of their Muslim faith, reports CBS Chicago.

According to a post on Facebook, the girls, who were wearing religious headscarves, had finished dinner at Pepe's Mexican Restaurant in Hickory Hills at the end of their fast for Ramadan.

Sawim Osman and her friends say they were walking out when a man in a booth began insulting them.

"We didn't say anything to him. We were completely calm, just walking past him. He's the one who instigated the whole incident," Osman told CBS Chicago.

In a video taken by one of the friends that was posted online, the man says, "If you don't like it in this country, leave."

"It's our home, too. What do you mean, leave?" one of the young women says.

When one of the friends tells the man he's "disgusting," he gets out of his seat.

Nour Jaghama, 16, says she's the one who confronted the man. When he stood up, she says, "I was like, 'No, he might actually get physical. I might get hurt."'

The friends say they'll share the video with Hickory Hills police.

The confrontation was upsetting to them, even 24 hours later.

A manager at Pepe's says the restaurant regrets the incident. Had workers been aware of it, they would have called police, he said.

The man hasn't been identified, says CBS Chicago.
