CONVERSE, Texas – Two people were critically wounded Monday afternoon in a shooting in the drive-thru lane of a Wendy's in Converse, police said.

Converse police Chief Fidel Villegas said a man in a car shot at two men in another car at 1:45 p.m. at the restaurant at 8646 FM 78. The men were apparently arguing about the length of time that one of them was taking in the drive-thru, police said.

The victims were taken to San Antonio Military Medical Center in critical condition, Villegas said.

The shooter left the scene, called police and turned himself in, Villegas said. The man is in custody and is being questioned.

Ralph Murphy, a Wendy's district manager, told KSAT 12 News that the manager on duty saw the argument escalate and moved customers away from the windows before the shooting.

No one witnessed the shooting or was near the gunfire, Murphy said.

The restaurant was closed after the shooting. It plans to reopen around 6 p.m.
