A Chicago man was arrested Saturday when he pulled out a submachine gun inside a convenience store on the 4000 block of West Madison.
According to the Chicago Sun-Times and Chicago Police, the man, 36-year-old Nahshon Shelton, became enraged when the store clerk asked him to pay the 22-cent sales tax on a two-liter bottle of soda Shelton was attempting to pay for.
Shelton pulled the gun out and began threatening the clerk and other customers. That's when the cops were called.
This "is my neighborhood. I'm tax exempt!" he reportedly told police.
