Mount Pleasant police were called to Ben Sawyer Boulevard's Triangle Char and Bar after an employee threatened other kitchen staff members with a knife, officials said.
No charges were filed in the incident, police said. But investigators were searching for the man Thursday to issue a trespass notice.
Police responded to the business at 1440 Ben Sawyer Blvd. around 11 a.m. Thursday.
The restaurant's chef told police that the kitchen staff had been two hours into service prep when the accused employee grabbed an 8-inch knife, pointed it toward the others and asked, "Do you have a problem with me?"
The Post and Courier has chosen not to identify the accused employee because he has not been charged with a crime.
According to police, the man threatened other employees while clutching the knife, saying, "I'll (expletive) you up."
The kitchen staff repeatedly asked the man to put down the knife and leave, police said. The employee eventually walked away after the chef threatened to call police, officials said.
Witnesses told investigators the man's outburst was unprovoked but that he often had a bad attitude at work.
The man was also going through family issues, witnesses reported to police.
The kitchen's staff members chose not to pursue charges in the incident, police said.
