A manager at a Buffalo Wild Wings eatery in Michigan has been fired after a video emerged on social media showing him choking a customer until he passed out.

The incident took place at the downtown Grand Rapids location on Ionia Avenue Northwest just before 11pm on September 6, but the footage only emerged on Saturday, after a former Buffalo Wild Wings employee acting on behalf of a current worker shared the surveillance footage on his Facebook page.

The 46-second recording without sound shows two staffers at the fast-food restaurant talking to a male patron dressed in a T-shirt.

After a few seconds, one of the employees, later identified as the manager, suddenly grabs the customer by the throat and pins him against the wall.

Shortly after, the patron collapses to the floor and the two eatery workers drag his limp body away.

Jean Lanfear, vice president of human resources at JK&T Wings, the franchisee of the Buffalo Wild Wings restaurant, said the customer who was throttled was 'very drunk' and was 'creating chaos'.

She added it was not the first time he had created a scene in the restaurant.

Having said that, Lanfear told WOOD-TV that the manager's actions were inappropriate and he has been terminated. She insisted that the now-former staffer 'doesn't embody the Buffalo Wild Wings culture.'

Former Buffalo Wild Wings worker Kennith Herrick said the video was recorded by a current worker who asked him to disseminate it in order to blow the whistle on incidents at the fast-food joint that he said had gone unpunished.

So far, no criminal charges have been filed against the unnamed former manager, but company officials are looking to speak to the man who was choked in the video.
