I used to pay cash to buy things as a kid, but now I don't even bring cash
with me when I'm shopping because paying with a credit card is much easier. These
days, credit card companies use promotions to appeal to customers. For example,
if you spend a certain amount of money this year with the credit card, they will
provide you something as a reward. You can even add your credit card to your
smart phone and pay by simply touching your phone to the card reader. Some of
the local restaurant owners in my town refuse credit card purchases, which is
illegal. They prefer cash for some reason. I won't go deep into that because
I don't want my writing to be too political or too serious.
