Even if almost nothing is known about the neuroanatomy of symboling, a great deal is known about the evolution of mind (or "minding," if mind is considered as a process rather than a thing), in which one finds symboling as the characteristic of a particular stage of development. The evolution of minding can be traced in the following sequence of stages. First is the simple reflexive stage, in which behaviour is determined by the intrinsic properties of both the organism and the thing reacted to—for example, the contraction of the pupil of the eye under increased stimulation by light. Second is the conditioned reflex stage, in which the response is elicited not

One of the odd things about some business organizations is that they spend so much money to lure new customers and spend so little to keep them after they’ve been landed. It just doesn’t make sense. Taking customers for granted is routine in some larger organizations, where mere bigness generates an attitude of indifference.
Loyal customers are an organization’s only protection against bankruptcy, and losing them because of neglect or indifference is downright sinful. Not only do satisfied customers continue to fatten the till, they often encourage others to buy. This is advertising that doesn’t cost a penny. And although there are always problems in giving good service to customers, maintaining their patronage (光顾) isn’t all that difficult.

A. It's not real that customers should be treated equal
B. It's not true that all customers are treated equal
C. Customers received equal treatment in the past
D. It's an old story that customers were treated equal
