Bubba tried a new shampoo for the first time and was so pleased with it that he mailed off an enthusiastic letter of approval to the manufacturer.

Several weeks later, he came home from work and discovered a large carton had come in the mail. Inside were free samples of the many products the same company produced: soaps, detergents, tooth paste, and more, along with a thank-you note from the manufacturer.

"Well, what do you think?" asked his smiling wife.

Bubba replied, "I think that next time, I'm writing to Toyota."
