Arby's decision to discontinue certain menu items, including ham, could be attributed to various factors. Menu changes in fast-food chains are often driven by factors such as customer preferences, supply chain considerations, cost management, and the need to streamline operations. While ham may have been part of Arby's menu at some point, its removal might have been due to lower demand or a strategic shift in menu offerings. It's important to note that specific details behind menu changes can vary and may not always be publicly disclosed.
