The introduction of accessibility guidelines and the opening of a new, more accessible store in Washington, D.C., demonstrates Starbucks' commitment to inclusivity and improving the customer experience. This move is likely to positively impact Starbucks' brand image and customer satisfaction, potentially leading to increased foot traffic and sales in the short term. The focus on accessibility also aligns with broader societal trends towards inclusivity, which could further enhance Starbucks' reputation and appeal.
