If Kolchek had negligently left Litisha alone in the spa prior to the incident described in the previous question, what defense to liability might Porter assert?

Shalene Kolchek bought a Great Lakes Spa from Val Porter, a dealer who was selling spas at the state fair. Porter told Kolchek that Great Lakes spas are “top of the line” and “the Cadillac of spas” and indicated that the spa she was buying was “fully warranted for three years.” Kolchek signed an installment contract; then Porter handed her the manufacturer’s paperwork and arranged for the spa to be delivered and installed for her. Three months later, Kolchek noticed that one corner of the spa was leaking onto her new deck and causing damage. She complained to Porter, but he did nothing about the problem. Kolchek’s family continued to use the spa. Using the information presented in the chapter, answer the above question.
