The video shows a middle-aged, athletic-looking white man berating both customers and a manager at a cavernous fast-casual restaurant called Fresh Kitchen. “Your staff is speaking Spanish to customers when they should be speaking English,” he says. “It’s America.” He adds: “I will be following up, and my guess is they’re not documented. So my next call is to ICE to have each one of them kicked out of my country.”

He said that he was paying for their “welfare.”

Officials in New York, which as a so-called sanctuary city limits its cooperation with immigration enforcement officials, quickly denounced the man’s action. Mayor Bill de Blasio reminded people on Twitter that New York was a welcoming city, where 8.6 million residents speak more than 200 languages. The city’s Commission on Human Rights, which investigates discrimination and harassment, said in a statement that it was “aware of the matter.” And the city’s commissioner of immigrant affairs, Bitta Mostofi, said in an interview that incidents like this, “while horrifying, are not commonplace — they also don’t belong in our city.”
