From my perspective, customers should be viewed as having great value. This is an entirely different thing from saying that the customer is always right (which by the way contains the additional team-killing undercurrent of suggestion that management will always back the customer over their own employees).

Some customers will use vast amounts of your time and constantly expect you to accommodate them. Especially in a small operation, the customers that cause disproportionate expense are toxic. These are the ones that you need to actively fire, and the assumption that every customer is a good customer (or that every customer is right) quite simply precludes this option.

You're both right.

"Every model is wrong, but some are useful"

While it's technically correct that the customer is not always right. It is useful to push this mindset on employees who directly interact with costumers. Leaving to your employees to figure the gray areas by themselves my cause you a larger net headache than telling them there's no exceptions, when it might not always be true.

This is to be expected. Even for isp bandwidth 5% of the customers use 95% of the bandwidth. But like internet bandwidths, the 5% that use the most are also the most vocal. People communicate and the bigger pain they are, the more they communicate with others.
