The incident took place Monday at a Walmart in Novi, Michigan. Novi Police Det. Scott Baetens told WJBK that the dispute was over a notebook in the back-to-school aisle. There was only one notebook left, and two shoppers were attempting to claim it when a verbal argument turned into pushing and shoving, and ultimately, one woman pulling out a gun, police said.
Customers and staff scattered after the gun was brandished, as can be seen in video capturing the chaotic scene shared by a bystander.
