It is a privilege not a right that customer patronize our business. To keep them waiting endlessly is indeed bad business.
It is bad business because there are so many close competitors that could edge you out of business if they are smart to quickly ride on your lapses.
The number one reason why customer might stop patronizing your product or services is poor customer service style that keeps them waiting.
People appreciate it when they are given maximum attention. By so doing, you reaffirm the fact that they are the reason why you are in business.
The rate at which people switch to other closely related products is on the increase just because their waiting tolerance limit was over stretched.
