Gillispie, a minor, was injured when two bottles of a soft drink exploded. The accident occurred as Gillispie was carrying the bottles to the checkout counter in the defendant’s self-service store. If a sale had taken place even though Gillispie had not yet paid for the goods, the store could be partially liable for the injury. Has a sale taken place? (Gillispie v. Great Atlantic and Pacific Tea Company, 187 S.E.2d 441, N.C.)
