“Customer is always right” isn’t a trump card for customers to win disputes with the staff. When it comes to matters of preference, yes, the customer is always right. Ketchup on ice cream? Great. Down jacket and shorts? Sure thing! If it makes you happy and you’re paying for it then you’re always right.

In most other matters though, customers are usually wrong. The idea that random people off the street know more about the products and the way a business should be run than the actual people selling said products and running said business is absolutely ridiculous.
