A customer at a Bronx 7-Eleven went on an anti-Muslim rant, telling an employee that he could have his gang member son stab him because Donald Trump won the election, sources told The Post.

The ornery customer flipped out when the worker confronted him as he tried to heat up his own food in a microwave in the East Fordham Road store in Belmont at around 9 p.m. Sunday night.

“Don’t look at me, I can do whatever I want you f–cking immigrant piece of s–t !” the man raged. “You Muslim. Go back to your country.”

The man continued harassing the worker, and even threatened to have his teenage son stab him.

“That is why Donald Trump is president; I can kidnap you, I have a 15-year-old son who is a Blood [gang member] who can stab you. All you see in your life are goats,” he said, according to sources.

The man then walked out of the store with his food. The worker called police, who are still investigating the incident.
