JACKSON, Mich (WLMI) A Jackson Arby’s was serving up more than roast beef recently. Last Friday, a customer at the North West Avenue restaurant found a piece of a finger inside his sandwich—Company officials say an employee apparently cut her finger on a meat slicer and didn’t realize a piece got wrapped-up in a sandwich. John Gray, VP of Communications for Arby’s, says they are investigating the incident. The store is open and the health department has given them the green light. Gray says they would like to apologize to the customer.
