A black woman says she was locked out of a Waffle House restaurant in Alabama while white customers ate inside.

Video posted by Jacinda Mitchell shows her pulling on the locked door of a restaurant in the Birmingham suburb of Pinson while others dined.

At one point, a white man inside the restaurant comes to the window and points, saying something unintelligible within inches of Mitchell.

It's unclear when the incident occurred, but Mitchell posts on Facebook that it was before the fatal shooting at a Waffle House in Tennessee and the arrest of a black woman at a Waffle House on the Alabama coast.

A statement from the Georgia-based restaurant company says an employee was wrong to lock the door. The statement doesn't address why the worker locked it, but spokesman Pat Warner said a company review would determine whether race was a factor.

Mitchell did not respond to a message seeking comment.

Mitchell's video was posted days after the arrest of a black woman, Chikesia Clemons, during a disruption at a Waffle House in Saraland, Alabama, prompted allegations of mistreatment by restaurant workers and officers.

The Alabama NAACP and an attorney for Clemons have questioned whether racial bias played a role in the arrest.
