Twelve years ago, Humm’s founder was having lunch with his sons at a Long John Silvers. He noticed satisfied customers would happily ring a captain’s bell on their way out, and in return employees would cheer with gratitude for the affirmation. The restaurant’s environment immediately changed, for the better.

Wouldn't the owners of this establishment appreciate the feedback as well? What if some days the bell rang more than others? What if the bells stopped ringing? With modern technology, there must be a way to capture all this feedback literally walking right out the door.
