It's not a statement of reality, it's a statement that you as a retailer need to treat your customers as if they're in the right, even if they're being assholes. If you treat them like assholes, they're going to stop giving you their money.
You need to be agreeable, polite, and patient with customers, even if they're being argumentative or stupid. Gently steer them towards the truth, but don't be blunt or insulting.
And if they want you to cook their delicious steak ultra well done until it's little more than tasteless shoe leather, and then they want to smother it in ketchup and salt, happily enable them to do so no matter how much you may be dying inside.
You dont need everybodys custom. Wed gladly lose customers if they demanded a well done steak in some of the restaurants I worked
in.
