WARREN, Mich. -- Diners at a metro Detroit restaurant got more than a full plate Sunday when a man walked in with a 5-inch knife in his chest.

Warren police said the 52-year-old man called 911 at about 10 p.m., saying he had been attacked in Warren but had just walked a mile to the Brayz’s Hamburgers in Hazel Park.

Restaurant employee George Mirdita said the man walked in, ordered a coffee and said he was waiting for an ambulance to come.

“It was like out of a movie,” Mirdita said. “It kind of freaked us all out here. Then, the customers realized it and they were all turning their heads in disgust.”

Police said the man told them he had been walking north on Warner Avenue near Eight Mile Road when another man approached him and demanded cash. The man told police that when he refused to hand over any cash, he was attacked and stabbed -- the knife being shoved into the left side of chest all the way to the black plastic handle.

Police said the man tried to get help at a nearby apartment complex, but when he didn’t find any, he called 911 from a pay phone at Dequindre and Nine Mile roads.

“Yes ma’am, could uh … is it possible to send an ambulance here?” the man is heard saying to a 911 operator. “There’s a knife stuck in my chest.”

The man goes on to tell the operator he thinks it’s a steak knife.

Mirdita said he can’t believe how calm the man was, and that he never complained of being in any pain.

“To come in with something stuck in your chest and order a cup of coffee, and sit down … he was mingling with the guy next to him,” he said.

The man was treated and police said he is expected to be fine.

Police said the man described his attacker as someone who was tall, was wearing a hooded sweatshirt and had a goatee.
