According to local authorities, a man in Chicago allegedly pulled a submachine gun on a convenience store clerk last weekend because he was upset about a 22 cent tax on a bottle of soda he tried to purchase.

ABC Chicago reports that 36-year-old Nahshon X. Shelton pulled the .22-caliber weapon weapon from his Gucci bag at the store on Saturday afternoon after the clerk told him the $1.79 two-liter of Pepsi would actually cost $2.01. Furious, Shelton reportedly brandished the weapon, yelling "This "is my neighborhood, I'm tax exempt!" and threatened to kill everyone present. 

The Chicago Tribune adds that he told one person he was going to shoot them in the head "three times." 

The entire ordeal was captured on surveillance camera, and Shelton was arrested and charged with unlawful use of a weapon by a felon and not having a firearm owner's identification card. When police recovered the gun, they discovered that it had a round in the chamber, eight rounds in one magazine and five in another.
