After trying a new shampoo for the first time, a guy fired off an enthusiastic letter of praise and 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 company produced: soaps, detergents, tooth paste, and paper items.
“Well, what did I tell you? They always send you free stuff when you write them a letter” his wife commented smiling.
Excited, the guy rushed to his desk, opened his computer and started typing something.
“What are you doing?” the wife inquired, “Dinner’s hot on the table.”
“I’m writing to General Motors!” exclaimed the guy.
