(Newser) – Fast-food ethics test: Three people who ordered food at a Taco Bell drive-thru in western Michigan found $3,600 in cash inside their bag instead. A Taco Bell employee mistakenly passed the money to the trio instead of their food on Saturday. (It was in a store bag awaiting deposit in a bank.) Kennidi Rue told local media that she and two friends thought about keeping the money but decided they would feel guilty if they didn't return it. "The store manager literally just burst out in tears," she says. "She was so happy we brought it back." Taco Bell hasn't publicly weighed in on the incident yet. (Read more Taco Bell stories.)
