Vincent sends Butch an email offering $200 for Butch to "clean my house." Not knowing Vincent has 2 houses, Butch looks up Vincent's address on Facebook, and cleans that house. After cleaning that house, Butch sends Vincent an email with an invoice attached for $200 for "house cleaning." Before receiving Butch's email, Vincent goes to his rental house that he wanted Butch to clean, and finds it still dirty. Vincent calls another cleaning service, and pays $300 to have them clean it that day. Upon checking his email later that evening, Vincent finds Butch's email, and deletes it. Butch sues Vincent for payment. How will Vincent defend? What claims will Butch assert? Who will prevail?
