After trying a new shampoo for the first time, Morris mailed off an enthusiastic letter of approval to the manufacturer.

Several weeks later he came home from work to a large carton in the middle of the floor. Inside were free samples of the many products the same company produced: soaps, detergents, tooth paste, and paper items....with a " thank you " note from the manufacturer.

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

"I think next time," Morris replied. "I'm writing to General Motors."
