Frank is building a home for Debby that under the original contract is to be completed by December 31. Debby found the plans for the home in a publication focusing on unique houses and is excited because it will be the only home of its type in the area. Because he underestimated the time needed for special and unique framing required for Debby's house, Frank tells Debby that he needs to hire additional workers in order to have the home done by that time and that she needs to pay him an extra $10,000. Debby says that she will pay. Frank finishes the home and asks for his $10,000. Debby refuses to pay. What is the likely result if Frank sues? Discuss whether you believe the result is ethical and equitable.
