Consumer: If you buy a watch at a department store and use it only in the way it was intended to be used, but the watch stops working the next day, then the department store will refund your money. So by this very reasonable standard, Bingham' s Jewelry Store should give me a refund even though they themselves are not a department store, since the watch I bought from them stopped working the very next day. The consumer's argument relies on the assumption that ['a seller should refund the money that was paid for a product if the product does not perform as the purchaser expected it to perform', 'the consumer did not use the watch in a way contrary to the way it was intended to be used', "a watch bought at a department store and a watch bought at Bingham's Jewelry Store can both be expected to keep working for about the same length of time if each is used only as it was intended to be used", 'one should not sell something unless one expects that it will function in the way it was originally designed to function']
