During the filming, the person operating the camera, who is an acquaintance of the employee, can be heard laughing.
Over the last week, two other companies have been forced to deal with similar incidents.
On February 7, Seven Eleven Japan Co. announced the dismissal of two male employees after an online video showed one of them using chopsticks to eat noodles direct from an oden hot pot in an outlet of chain 7-Eleven. Two days later, the company said that it was considering legal action against the employees.
Last week, two employees of large sushi chain Kura Sushi resigned after the emergence of a video online that showed them tossing a sliced fish into the trash and pulling it back onto a cutting board in the kitchen of an outlet in Osaka Prefecture. "We will work to prevent a recurrence of the same incident," the operator of the chain said.
