A Colorado police officer got so impatient with his delayed fast food order that he allegedly pulled a gun at a McDonald's drive-through, local media reported.

Police in Aurora, Colo., say they are investigating the May 21 incident, including the allegations that a Denver officer menaced a restaurant employee with a gun, but no charges yet have been filed. Aurora police did not release the name of the officer.

Local media reported that the Denver cop was with a fellow officer, both off duty, when they placed an early-morning order at a McDonald's in Aurora.

They waited and waited, and then one of the officers got agitated and flashed a gun, employees told FOX13. They finally received their food, paid for it and drove off.

Souces told FOX13 that both officers deny doing anything wrong. One officer remains suspended without pay, according to CBS 4.
