In any transaction where value is exchanged for value, the agreement is mutual, not one way. I’ve heard too often that the “customer is always right.” If that is the case, then this is the truth:
If I, a provider of consumer goods and services (value) exchange my goods/services (value) with another consumer for his/her currency (value), then I, too, am a consumer purchasing his/her currency (value) with my goods/services (value).
The exchange is value for value under the terms of agreement and the agreement is mutual. So then as he/she who buys my goods/services is a customer, then I who buys his/her money am a customer, too, and the customer is always right.
