I agree. Way too many companies don't realize the value of customer service. While it may look like they are doing the nice thing, they are simply doing the RIGHT thing, not only as a way of doing the right thing as a deal, but best business practice.
Fly by night short sited, or bully business approach doesn't work well, and certainly doesn't give a good reputation and on edge and ready to jump on the next supplier for better service.
This is one of the best and least costly ways, not only to retain, but also do the grass roots true valued marketing of the brand. Reputation is important. It also shows a business that has pride in how they do things. Business actions should have a sense of pride behind, and never a sense of arrogance.
