Taco Bell customers are used to menu items going missing. The brand is well known for its strategy of periodically retiring and reinstating popular menu items to keep things fresh. For example, the chain stopped serving the fan-favorite Mexican Pizza last November , regardless of its iconic status, while their viral Nacho Fries will soon make their seventh limited-time appearance on the menu in just four years. But customers have recently been noticing a different kind of menu shakeup: shortages of essential ingredients. Social media platforms have recently been buzzing with stories of Taco Bell locations running out of basic supplies. Fans took to Twitter to complain about nationwide shortages of beef, chicken, and 10-inch tortillas at the chain a few weeks ago.
