Question: Bain lived in Bristol Harbor, a resort area along the Atlantic coast. She entered into a written agreement to sell her daily catch of fresh lobster at an agreed price to a local restaurant owner during the tourist season. At the end of the tourist season, Bain sued the restaurant owner for an additional $2,000. At the trial, she claimed that shortly before signing the contract, the restaurant owner orally agreed to pay her a $2,000 bonus. Can Bain introduce the oral agreement as evidence and collect the $2,000 bonus?
