Ismael Dushan was at the Levels Barbershop on May 17 when he says he began to argue with the unidentified barber about trimming his beard. The stylist “was just really negative,” Dushan told the New York Daily News. The 33-year-old is reportedly a practicing Muslim and refused to allow his beard to be cut.
