The phrase "the customer is always right" is widely misquoted — its original form includes a crucial qualifier: "in matters of taste." Attributed to Harry Gordon Selfridge and other early 20th-century retailers, it was meant to counter paternalistic merchants who imposed their preferences over customers' subjective choices. The principle applies to taste-based decisions in retail, food, and creative services, but not to factual disputes, safety, legal compliance, or staff mistreatment — where other standards must hold.
