The Bitter Experience of Restaurants with AI Mistakes
Tehran - BORNA - The restaurant industry is rapidly embracing artificial intelligence to enhance customer service and improve overall experience. However, the journey has not been without challenges, as recent experiences show that AI-driven solutions still face limitations and require careful integration with human staff.
In recent years, restaurants have increasingly turned to advanced technologies, particularly AI, to improve efficiency, reduce costs, and elevate customer satisfaction. Voice-based AI ordering systems have been deployed in many fast-food chains to speed up service and minimize human error. Yet, practical applications reveal that deploying AI in direct customer interactions comes with risks and complexities.
According to Bor¬na News Agency, Taco Bell, one of the largest fast-food chains in the United States, introduced AI-powered voice ordering systems in more than 500 locations in 2024. The goal was to cut wait times, improve order accuracy, and enhance overall customer experience. At first, the initiative was welcomed by customers impressed with the innovative approach and faster service. However, problems soon surfaced, attracting attention from media outlets and social networks.
One of the most notable issues was the system’s inability to handle unusual or prank orders. A viral TikTok video showed a customer successfully ordering 18,000 cups of water through the AI system highlighting flaws that quickly drew widespread criticism. Additionally, some customers complained that the AI repeatedly prompted them to add drinks to their orders, even after their requests were complete. These frustrations led to growing dissatisfaction and mistrust among users.
In response, Dane Mathews, Taco Bell’s Chief Digital and Technology Officer, acknowledged that the company is reassessing its approach to AI in drive-thru services. He emphasized that while AI can be effective in certain contexts, it does not always perform reliably, particularly during peak traffic hours when human staff may be more efficient. Mathews also stressed the importance of employee training to handle AI errors quickly and confirmed ongoing collaboration with Nvidia to refine AI applications in the restaurant industry.
Beyond Taco Bell: Other Restaurant Experiences
The AI experiment is not unique to Taco Bell. In Iran, the adoption of AI in restaurants is still in its early stages, but examples exist. Several restaurants and fast-food venues in Tehran employ robots for ordering and serving meals. Despite these innovations, financial constraints, lack of infrastructure, and limited workforce training remain barriers to widespread adoption.
Global fast-food giants like McDonald’s and Wendy’s have also piloted AI-driven ordering systems in select locations to boost efficiency and enhance customer service. Yet, they too encountered problems ranging from inaccurate order recognition to system malfunctions forcing them to reconsider full automation. Many have since shifted toward a hybrid approach, combining AI with human staff to ensure reliability and customer satisfaction.
The experiences of Taco Bell and other brands illustrate the challenges of using AI in direct customer-facing roles. While AI offers substantial benefits, it must be deployed cautiously, with careful attention to context and customer expectations. A hybrid strategy where AI and human employees complement each other appears to be the most effective solution for the future of restaurant service.
