A McDonald's manager was threatened with a gun by customers who were angry about the salt on their chips.
Police were called to a branch of the fast food chain in Houston, Texas, last week following the bizarre encounter.
Officers quickly established that the suspects had been in a "verbal altercation" with staff over their order.
CCTV and eyewitnesses then revealed to the authorities that the pair had pulled a gun at the drive-thru window.
Constable Mark Herman said in a statement that Davion Guillory, 23, and Trekyia Cohen, 25, were then identified and arrested.
Both have since been charged with aggravated assault with a deadly weapon, the Harris County Precinct 4 officer confirmed.
