On top of what j5r5myk mentioned, there is a fairly good record of the origin on “the customer is always right,” (described on Wikipedia) because it was something like a moderately well known person’s catchphrase, in an era when newspapers and marketing existed. https://en.m.wikipedia.org/wiki/The_customer_is_always_right https://en.m.wikipedia.org/wiki/The_customer_is_always_right There’s some quibbling to be had about the meaning, but it puts it closer to “assume good faith” or something like that, rather than reducing it to just preferences. > The earliest known printed mention of the phrase is a September 1905 article in the Boston Globe about Field, which describes him as "broadly speaking" adhering to the theory that "the customer is always right". > However, John William Tebbel was of the opinion that Field never himself actually said such a thing, because he was "no master of idiom". Tebbel rather believed it probable that what Field would have actually said was "Assume the customer is right until it is plain beyond all question that he is not."
