Case #4: Justin and his friends are out for a night on the town in Niagara Falls. They have dinner and go to the casino and after having a few drinks are walking back to their hotel. They see a sign advertising Fortune teller/Psychic services and decide to go in. The Psychic, Esmerelda, tells Justin good news is heading his way and it is likely he will get a promotion and raise at work and his relationship is about to get much stronger with marriage a possibility. All the friends enjoyed the reading and headed home the next day. A few months later after Justin had been laid off from his job and found out his girlfriend was leaving him he decided to sue the psychic for not upholding her side of consideration in their unwritten contract. What are your thoughts on this? Case #5: Cara bumped into Cam at a party and offered to sell her beloved Camaro to Cam for $14,000. Cam knew the car and believed it to be worth at least $18,000. Cam low-balled Cara as he stuck out his chest and, somewhat arrogantly, said "That ain't gonna happen. I'll give you $9,000.", Cara, understandably offended at Cam's rude arrogance, said 'no'. A few minutes later Cam sheepishly walked over to Cara and said "I'll pay your full asking price, Cara - $14,000". Cara, still offended from his earlier rudeness, said she wouldn't sell it to Cam. If Cam sues Cara for the right to purchase the car, who wins and why
