Carol Wojtyla was on a walk and stopped to talk to a neighbor Mother Theresa.  They started talking about the weather. Mother Theresa told him that she is worried about winter because she just had knee surgery and doesn’t think she will be able to shovel snow. The next day it snows and Carol knocks on Mother Theresa’s door and offers to shovel her walk. After shoveling the walk, Mother Theresa pays Carol $20. It snows for the next 5 days and Carol returns each morning to shovel Mother Theresa’s walk.  Each time he is paid $20.  Now, over the course of the next month, it snows off and on and Carol shovels her walk each time it snows. However, Mother Theresa does not pay for the recent months snow shovels. When Carol asks, Mother Theresa replies “I thought you were just being kind” and further explains that she never intended to pay for each snow shovel. Carol files a lawsuit in small claims court (Wojtyla vs Mother Theresa) to recoup payment for his service. Which best describes how the court would rule:

Walter White hires Jesse Pinkman to paint his house.  Walter and Jesse enter into a valid contract where Walter agrees to pay Jesse $2,500 for the job. After completion, Walt believes (in good faith), that the paint job was defective and withholds the payment. He calls Jesse and says “that job you did was not good enough.” Jesse responds “yo yeah it was man. I don’t know what you expect of me. Now show me some respect and pay me or I am calling my lawyer.” Walt says “Jesse, don’t be an idiot. I am going to call my lawyer too!” The parties bicker back and forth for a while. Walt finally says “fine, Jesse. Just listen to me. Instead of suing this out in court, I will offer you $1,000 in full settlement of the claim.” Jesse, accepts, despite that the reasonable value of his services was $2,500. Walt sends a payment in the form of a check to Jesse of $1,000 with the words “in full settlement of the claim” written on the check. Jesse accepts and cashes the check. Jesse then sues Walt for the remaining $1,500. Will Jesse be successful in a lawsuit asking for the remaining $1,500?
