A video of a KFC female employee showing her middle finger to customers who moved the tables at an outlet went viral on social media, reported Sin Chew Daily.
The eight-minute video showed the employee staring at the recording device, making an obscene hand gesture and turning away.
The paper added that the videographer and initial uploader of the video was believed to be a student.
According to the note uploaded with the video, the incident happened at one of the outlets in Ampang.
"Some 20 students visited the outlet after their extra co-curriculum activities, and in order for them to sit together, some of them had combined the tables, but they were reprimanded by the employee.
"She told us that this would affect other customers, but we were sure that we did not cause any inconvenience to others. She later shouted at us, asking us to rearrange the tables and clear the bones and serviettes before leaving," the note read.
The video has also been brought to the attention of KFC Malaysia Senior Vice-President Ling Mee Jiuan, who posted in the restaurant's official Facebook that the employee has been suspended and an internal investigation was being carried out.
