Starbucks (NASDAQ: SBUX) investors had some big concerns heading into the company's fiscal 2022 third-quarter earnings update (for the quarter ending July 3). The coffee giant has been losing market share to rivals like McDonald's (NYSE: MCD) as consumer preferences shift toward drive-thru and on-the-go ordering. Starbucks' value proposition has traditionally stressed the in-store experience, making it hard to see how the company can thrive in this new selling environment.
