You are a chicken farmer and sign an agreement with a local chicken rotisserie restaurant owner to sell a large quantity of organic chickens to him every month. The written contract is specific as to the price and the number and size of chickens to be delivered each month and states that they will be "good quality" organic chickens. However, when you send the first shipment, the restaurateur says they are not of high enough quality, and he will not pay you. You reply that your chickens meet United States Department of Agriculture (USDA) guidelines for being "Grade A," which is the highest grade, and they are also certified to meet USDA organic standards. The restaurateur claims a) your chickens are not of the quality he had in mind, b) the contract does not say anything about the USDA, and c) his willingness to pay depends only on his own ideas of what constitutes good quality. What do you think should have been added to the contract to avoid this kind of dispute? Will you be able to get paid for your chickens if you file a lawsuit seeking to force the restaurateur to pay?
