No names released yet, but Whataburger issued a statement a while ago saying the person was no longer with the company.
Whataburgers statement
We were appalled to hear of an employee refusing service to two officers, as we have proudly served first responders across our system for decades. As soon as we heard of this isolated incident, we began our own internal investigation overnight. The employee that refused service is no longer employed with Whataburger. Weve also invited the officers back today so we can apologize in person and make this right.”
