Whoever came up with the phrase “Customers are always right” is a complete and utter moron! Because in actual fact, 99.99% of the time they are wrong. They like to think that they have the right to be “always right” because they are paying for your goods and services, and that you should treat them like Gods, but they are just like anyone else you’d meet on the street.
I’d treat anyone with kindness, understanding, and respect until they give me a reason not to. This should go for customers who are unreasonable, disrespectful, up-tight, stubborn, cocky imbeciles.
"Do unto others as you would have them do to you" - if you want good service, then act like a decent human being. Don’t wave your cash at me and expect me to roll out the red carpet for you.
