LEWISVILLE, Texas (AP) — Whataburger has fired a worker who refused to serve two off-duty, in-uniform law enforcement officers who stopped at a Dallas-area restaurant.

San Antonio-based Whataburger apologized Wednesday and invited both officers to return to the Lewisville location for a free meal.

Milford police Officer Cameron Beckham and Michael Magovern, who’s a reserve deputy with the Strawn city marshal’s office, say they were refused service Tuesday night. An employee allegedly told the men that “we don’t serve police” and refused to wait on them.

The officers were headed to a construction area to work overnight traffic security and had stopped to eat. They then went to a Dairy Queen.

A Whataburger statement says the company was appalled to hear of the employee’s actions and that all restaurants proudly serve first responders.
