Drive-through fast food vendor Sonic, known for their creepy television commercials, made the silver screen in a less appetizing way in Corpus Christi, Texas.

According to Jessica Hamilton of the Houston Chronicle, when the Cortez family pulled up to a Sonic Drive-In window on Saturday, they expected to be handed the four drinks they ordered. Instead, they arrived at the window to find their drinks were already being eyed by a furry friend.

In a viral video posted to Facebook, the family can be heard screaming as 14-year-old Christian Cortez records a mouse walking on the fountain drink machine at the Ayers Street location. An employee with a long stick attempts to move the mouse off the machine.

“I was really shocked to see it, especially since it was right next to our drinks,” Cortez said. “Once it went around the fountain machine an employee was still trying to give us our drinks. We told them we wanted a refund.”

The family got their money back.

A spokesperson for Sonic issued a statement Tuesday morning, stating the franchisee at the location has increased pest control measures, including two visits over the weekend.

“The drive-in is currently in good standing with the Health Department and the franchisee takes food safety very seriously. All food safety issues are acted upon immediately,” said Jason Cook, manager of communications for Sonic-In. “They appreciate the trust and confidence customers place in Sonic every day to serve them delicious and safe food. They take pride in being a good community partner and are proud of the service their employees provide to customers every day in Corpus Christi.”

Uh-huh.
