The regular customer normally comes to the organization to satisfy a majority and easily identified need: food, transportation, thirst, recreation, recovery of optimal health, etc., while in the case of the internal customer for most people, even for many of the internal customers themselves, they only come to organizations to acquire money, when in reality, they seek to satisfy needs for affiliation, security, self-esteem, self-realization, power.
In the case of the external customer, the scope of the set of needs is often wider and better known. When it comes to the internal customer, although many authors (Maslow, Mac. Gregor) have described the set of needs that can be satisfied through work, for most people the only or the main purpose pursued by a worker is the satisfaction of a physiological need by obtaining money, and they rarely recognize in others the needs for security, social, self-fulfillment and self-esteem.
