3. “Remember
Me?”
I'm the fellow who goes into a restaurant, sits down and patiently
waits while the waitresses do everything but take my order. I'm
the fellow who goes into a department store and stands quietly
while the sales clerks finish their little chitchat. I'm the man who
drives into a gasoline station and never blows his horn, but waits
patiently while the attendant finishes reading his comic book.
"Yes, you might say, I'm a good guy. But do you know who else I
am? I am the fellow who never comes back, and it assumes me to
see you spending thousands of dollars every year to get me back
into your store, when I was there in the first place, and all you had
to do to keep me was to give me a little service; show me a little
courtesy.“

specificities of each culture and each market. Well
aware of the importance to have an offer with specific
products to meet the needs and tastes of consumers
from different cultures, the fast-food giant has for
example: a McBaguette in France (with french baguette
and Dijon mustard), a Chicken Maharaja Mac and a
Masala Grill Chicken in India (with Indian spices) as
well as a Mega Teriyaki Burger (with teriyaki sauce) or
Gurakoro (with macaroni gratin and croquettes) in
Japan

• Attitude
• Personality
• Learning : For example, if you are sick after
drinking milk, you had a negative experience,
you associate the milk with this state of
discomfort and you “learn” that you should
not drink milk. Therefore, you don’t buy milk
anymore
28. economic modeL
• In this model, consumers follow the principle of maximum
utility based on the law of diminishing marginal utility.
Economic man model is based on the following effects −
• Price Effect Lower the price of the product more will be−
the quantity purchase.
• Substitution Effect Lower the price of the substitute−
product, lower will be the utility of the original product
purchase.
• Income Effect When more income is earned, or more−
money is available, quantity purchased will be more. The
economic theory of buyer’s decision-making was based on the
following assumptions:
29. Chapter 21 - Consumer Choice 29
Utility Theory
• Utility
– The want-satisfying power of a good or service
• Utility Analysis
– The analysis of consumer decision making based on utility
maximization
• Util
– A representative unit by which utility is measured
30. Chapter 21 - Consumer Choice 30
Utility Theory
• Marginal Utility
– The change in total utility due to a one-unit
change in the quantity of a good or service
consumed
Marginal utility =
Change in total utility
Change in number of units consumed

Observe
Diminishing
Marginal
Utility
40. • As consumer resources are limited, he would allocate the
available money which will maximize the satisfaction of his
needs & wants.
• Consumers have complete knowledge about the utility of
each product and service, i.e., they are capable of completing
the accurate satisfaction that each item is likely to produce.
• As more units of the same item are purchase the marginal
utility or satisfaction provided by the next unit of the item will
keep on decreasing, according to the law of diminishing
marginal utility.
• Price is used as a measure of sacrifice in obtaining the goods
or services. The overall objective of the buyer is to maximize
his satisfaction out of the act of purchase
