Paul decided he did not want the jeans he had purchased from a large discount department store. He had worn them three times over the past three months, had laundered them, and then decided he just did not like them. The jeans fit him fine and there is nothing wrong with them. He takes the jeans back to the store even though the store has a return policy of 30-days. He does not present a receipt but states that he purchased the jeans a couple weeks ago. He argues vehemently with the store manager that the store has a legal obligation to return his money and has a "no questions asked" policy as to why the merchandise is being returned. The store gave him a full refund of his money. Which statement is correct?

Paul's conduct was not unethical since the store's policy of giving full cash funds with no questions asked applied.

Paul's conduct was unethical.

Paul's conduct was ethical since he believed the store had a legal obligation to return his money.

Paul's conduct was ethical since he didn't like the jeans and wanted to return them.
