Starbucks baristas are implementing a new system to speed up service and reduce wait times of up to 40 minutes for customers' orders. The system includes changing the production order of hot and cold drinks, with a focus on prioritizing orders based on when they were received. Additionally, Starbucks plans to assign a "play caller" to help streamline operations and alleviate bottlenecks during peak hours. The company also aims to increase customer engagement through its mobile app and recently introduced a value combo meal option. The changes come in response to complaints from both customers and workers, as Starbucks faces declining sales and foot traffic. The company's new CEO has been criticized following a decrease in stock price and revenue forecast cuts. Former CEO Howard Schultz has called for a revamp of US-based operations to address the challenges faced by Starbucks.
