A group of Muslim teenagers were verbally accosted in a Mexican restaurant, apparently because of their headscarves, after breaking their Ramadan fast, according to a video they shared of the incident.

“We didn’t say anything to him. We were completely calm, just walking past him. He’s the one who instigated the whole incident,” one of the teens, Sawim Osman, told local TV station CBS2.

The president of Pepe’s in Hickory Hills, Robert Ptak, apologized on behalf of the company.
