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