According to investigators, the 26-year-old picked a fight with another customer inside the store. At some point, Dressler pulled a knife.
Another customer, Billy Dunkelberger, 21, tried to help. Officers said Dressler then pointed his knife at him, so Dunkelberger pulled a gun.
No one was hurt, and police arrested Dressler. He's charged with aggravated assault.
Dunkelberger is not facing any charges because he's a gun permit holder."
