The chef decided to launch a new special on his menu. He needed to be sure it would be well received. He didn’t know how to quantify the impressions of the people on his payroll. Instead of haranguing his staff about their lackluster opinions, he decided to offer free samples to his guests. While his patrons waited for their meals to be presented, the chief asked them to please taste his new creation. If they chose to eat the new entrée, he knew it would be a great addition to his menu.
