No, no they're not. The customer is frequently extremely wrong. That saying originated in sales and just meant that if the customer wants to buy something don't talk them out of it, even if what they want seems stupid to the salesman. It's not "I'm buying something so I can be completely unreasonable but I'm still correct! no matter what"
As an example of how a customer might be wrong: the customer could fire off half-cocked and try to trash a business before ever contacting them (because the CS is done via chat instead of a phone number boo hoo), harass the CEO on social media (before actually contacting CS), receive amazing customer service and get a refund even though the mistake was with another company and there is no proof of what the customer claims, and then still go on a forum and without even acknowledging how wrong they were shift smoothly into accusing another company that's making $61,000,000,000 shipping 5,500,000,000 packages PER YEAR of trying to commit fraud and screw them out of $20 and bragging about what a hero they are for standing up to the man.
That's one way a customer could be pretty wrong on every level.
What's your problem? Guess I can add you to my ignore list, lol.
