We should stop saying "The customer is always right" because it's not true - tchncs

In the grand scheme of things, the customer may have slightly more pull than the cashier ringing up their order, but it’s the CEO and the board of directors that control the narrative. That’s why we’re getting bigger and less fuel efficient vehicles, bigger and more fattening meal portions in restaurants, and bigger less affordable houses.

The whole saying is actually “The customer is always right, in matters of taste.”
This is the correct answer. All of the other explanations are dancing around this: no matter what YOU think of a particular product, if a customer is willing to buy it then YOUR opinion must be the wrong one.
Indeed. But it somehow morphed into "customers can abuse and harass staff at customer service jobs"
