An expectation gap generally arises from an impediment to communication between a supplier and a customer or where the product simply does not match up to what was anticipated. It is incumbent on those selling the goods to explain clearly what is being purchased and the purpose to which it will be applied.
If a customer has the wrong end of the stick, many theorists espouse that you have them leave thinking they were right all along. The rationale is that they will be back for more at a later time. What this doesn't consider, however, is the time and effort that is invested in dealing with a customer who just doesn't understand. In many cases, it may be more beneficial for you that you politely direct them to your opposition!
It is important to understand the real cost of doing business with particular customers because it might be that the work required to keep them happy is a cost which exceeds the benefit of keeping them.
I guess the key is finding balance. And it will always be a positive if your business is known for going the extra mile, but my advice is not to get caught in situations where your investment in the sale exceeds the margin returned to you.
