Waffle House is in trouble, again, after a black woman says she was locked out of one in Pinson, Alabama.

Jacinda Mitchell posted a Facebook video of her pulling on a locked door Saturday, April 21, while white customers ate their food indoors.

“I am at Waffle House in Pinson and they have the door locked. And they have customers in here and they are saying that they’re closed,” Mitchell said in the video. “The customers are eating. They happen to be all white customers only and I am an African American.”

A cook can be seen preparing food while a waitress, who Mitchell says refused to open the door, walked through the kitchen.

WBRC spoke to the waitress, Shelby, who claims she locked the door because they work short-staffed, and she was overwhelmed. She says race had nothing to do with her decision.

The waitress added that she regrets locking the door, and had things been less frenetic, she would have been more than happy to have Mitchell in the restaurant.

Waffle House spokesperson Pam Warner released a statement that said the waitress was wrong to lock the door, and the chain is investigating the incident.

“We are aware of the incident at our restaurant in Pinson, Alabama, on April 22, 2018. We have launched an investigation to gather all of the facts," Warner said. "Waffle House is a welcoming place for everyone, and we are fortunate to enjoy a very diverse and loyal customer base who we do our best to serve every day. The employee involved should not have locked the front door at all and should have certainly opened the door for the customer when she arrived. We will get the facts and take appropriate action quickly.”
