Sabrina goes to Costco to purchase food for her upcoming 4th of July party. While at Costco, she samples some of their frozen brie cheese appetizers, which a Costco employee takes out of the package and then cooks to show customers what the product is. Sabrina decides to purchase the item based on trying the sample. At her party, she notices that the product she purchased tastes extremely different and has a different cook time. Assuming that Sabrina purchased the same product she tried, what would be her best argument for returning the product for a refund?
