A Wendy’s customer used a chair to thwart a would-be robber in Yuba City, California, on Christmas Day.

The suspect, who had a knife, threatened the staff at the Wendy’s restaurant while wearing a bag over his head, KTXL reported.

“So I kept an eye on him,” said the good Samaritan, who called himself Daniel.

He said, “And then I noticed that he had a knife in his right hand. And he cut in the front of the line and went up to the cashier, brandished the knife, and said, ‘Give me the money.’ And then about two seconds later, he turns to somebody on his left and says, ‘She’ll take care of you in a minute.' And that’s when I brought the chair down on his head.”

“And when I saw the knife I thought, ‘Look at all these people in here. I don’t want this to turn into somebody’s Christmas memorial.’ And yeah, it was about that time, I took a couple steps with that big chair in my hand and brought it down on his head,” he said.

The suspect then ran out of the restaurant and got into a car, described as an early 2000s or late 1990s Honda.

“If anybody out there knows a friend who got a gash on the head last night, that was probably the culprit,” Daniel added.

“That’s a very traumatic experience, and he helped us instead of standing back and watching it,” said cashier Erika Farris about the incident.

The suspect has not been identified. Those with information are urged to contact the Yuba City Police Department.
