When it comes to bang for your buck, consumers are like watch dogs. Some take it so far that they even decide to sue the brand if they feel like they're getting cheated. Last year alone we saw suits get filed against Starbucks for not pouring lattes to the brim and another against Barilla for under-filling its pasta boxes. And before that, Subway was court-ruled to measure all of its footlong sandwiches to prove they are, in fact, 12 inches. Even earlier this year, a woman sued the company that owns Mike and Ikes for selling candy boxes that are half-filled with air. And now, Hershey's is in the hot seat for the same candy box issue. In particular, Whoppers and Reese's Pieces are the subject of criticism among consumers who allege that the candy company is misleading customers, Consumerist reports. To be more specific, one man in Missouri has filed a federal class action lawsuit that alleges Hershey's has under-filled the Whoppers boxes by 41 percent and the Reese's Pieces boxes by 29 percent. Meanwhile, Hershey's attorneys argue that "consumers are well aware of the fact that substantially all commercial packaging contains some empty space." The claim states that this extra space is not necessary to protect the product inside, unlike fragile potato chips or pretzels. But the brand counters this point as well, saying, "It is not possible to view the product packaging without also seeing the net weight and quantity disclosures" and even further elaborating that "any consumer would recognize immediately upon picking up a box of Reese's Pieces or Whoppers that its contents rattle noticeably and audibly with every movement." Stay tuned for more details as the case moves forward in the judicial system. Who knows — maybe there will be some free chocolate at the end of all this.
