Everyone knows that ranch is the preferred dipping sauce when it comes to McDonald’s french fries. Okay, fine it might not be for everyone. But no matter what condiment you choose, getting less than you think you deserve doesn’t mean it’s okay to shoot the drive-thru window with a BB gun.

KRCR-TV reports that just such an incident occurred at a California McDonald’s after a couple didn’t receive ketchup with their order.

At around 12:15 a.m. on Tuesday, employees say a red car occupied by a man and a woman left the fast food restaurant upset over ketchup not being included in their order.

Shortly after the couple drove off, employees realized the drive-thru window had been shot out.

Upon police arrival it was determined that the window had two small holes in the glass and a small BB gun projectile was found on the ground near the window. Police also reported that two vehicles in the parking lot were damaged by BB gun projectiles.

About an hour later police officers located the red car in a nearby Walmart parking lot with the man and woman inside.

A search of the vehicle found three BB gun handguns, BB gun projectiles, McDonald’s food packaging and drinks and a McDonald’s receipt for a recent purchase close to the time of the reported shooting.

Both individuals were arrested on unrelated charges, but local officers say they would seek additional charges regarding their suspected involvement in the shooting.
