Having the correct number of items at a supermarket checkout lane can be serious business.

Authorities say two women got into a fight at a Monmouth County ShopRite after one accused the other of having too many items in an express checkout lane.

The fight broke out shortly before noon Thursday, according to Howell Township police.

Police say that a 45-year-old Howell woman challenged a 43-year-old Brick woman over the number of items she had at the checkout. Their verbal dispute soon turned physical, with both women allegedly throwing punches and biting each other.

Witnesses said that the Brick woman also scratched and bit the leg of a 43-year-old Freehold Township woman who tried to intervene. All three women were treated for minor injuries.

The two women involved in the fight were both charged with disorderly conduct. The Brick woman was also charged with simple assault. Their names were not released.
