A New Jersey woman is behind bars for stabbing a customer at a Marshalls store parking lot with a kitchen knife when her apparent frustration boiled over.

25-year-old Amber Thompson was charged in connection with the stabbing incident, which took place on Oct. 11 at a Marshalls department store in Hudson County, New Jersey.

Local police say that the violence broke out after Thompson allegedly started an argument with a fellow customer standing in front of her in the checkout line.

Thompson, who was purchasing a set of kitchen knives from the store, got into a dispute with a female customer about “the speed of the checkout line,” according to NJ.com.
