A recent Mintel study, for instance, showed ready-to-drink coffee has posted five straight years of double-digit sales growth, outpacing the specialty coffee shop sales growth tracked by Euromonitor. Meanwhile, as Starbucks has grown, it has faced the mounting challenge of training its employees and maintaining the same level of customer service and experience. For instance, even though the company recently shut its more than 8,000 company-owned U.S. stores to train nearly 175,000 employees on unconscious bias after a Philadelphia manager called the cops on two black men, the response from both employees and customers has been mixed. (Just look at Starbucks's painstaking responses to each Facebook post applauding or faulting it for the move.) With its recent move to officially declare its Use of Third Place policy to welcome anyone, paying customer or not, to its stores, the chain also needs to figure out who and how it wants to please without alienating its loyal customers.
