For Questions 2-4: Your business enters into a contract with Bad Frog Brewery, Inc., to distribute their beer, "Bad Frog Beer." The label on their beer bottles, as depicted above, has a frog giving the finger as that gesture is normally meant. You succeed in obtaining contracts with local grocery and convenience stores to sell Bad Frog Beer distributed/delivered to them by your business. However, using a little-known ordinance prohibiting "the display or furthering the display of products with obscene gestures in retail establishments in the county," and making violators subject to a fine of $100.00 per displayed item, Polk County issues citations to several of the grocery and convenience stores to whom you have sold Bad Frog Beer causing them to return the Bad Frog beer you sold them and rescind their contracts with you. You have also been issued citations for distributing the beer with the Bad Frog labels. You consult with a lawyer and he advises you to bring a lawsuit challenging the citations and fines issued by Polk County to the grocery and convenience stores and your company. 2. Which of the four requirements for valid contract formation could your grocery and convenience store customers claim that the contract they entered into with you for the purchase of Bad Frog beer was not valid.
