Do you think that a customer and consumer are different?

by dictionary definition we can see the following:

CUSTOMER-noun1.

a person who purchases goods or services from another; buyer; patron.

2.

Informal. a person one has to deal with: a tough customer; a cool customer.

CONSUMER-noun1.

a person or thing that consumes.

2.

Economics. a person or organization that uses a commodity or service.

3.

Ecology. an organism, usually an animal, that feeds on plants or other animals.

Every customer is a consumer but not every consumer a customer. Customer is one who is brand loyal, who has made a custom to purchase a particular company's product/services. thus customer is a sub set of consumer.

A customer usually has a choice where he/she spends their money. A consumer may have to buy from a monopoly. Politicians love to call consumers customers.
