Pаul (P) lives in Lоs Angeles, CA аnd hаs decided tо purchase an expensive pоrtable pizza oven from David (D), his neighbor. After talking on the phone, they agree to a purchase price of $1,000. Since Paul has never made homemade pizza, David agrees to provide Paul with 2 lessons as part of the contract. Paul tells David he wants to watch him using the pizza oven to ensure it works before taking possession or providing payment. David invites Paul over for a homemade pizza dinner to see the oven and taste how delicious the pizza is. During the cooking session, Paul notices a steady stream of black smoke coming from the oven. Paul tells David he will not pay him until this is fixed. Believing David will fix the oven, Paul excitedly purchases a new dough mixer, an expensive chef jacket, and a large wood cutting board to use while making homemade pizza. The next day, David receives an offer for his pizza oven from another buyer for $1500 as is. David accepts this offer and delivers the pizza oven to the second buyer. Questions: Is there a legally enforceable contract between Paul and David? Which law applies? Are there any defenses available to David? What, if any remedies are available?
