No more than a dozen customers died. Our customers are leaving us. Income is shrinking. If we don't get the food poising rate back up our business will shrivel to nothing. We face the end of our careers.
Businesses build their success on living, breathing, healthy, happy customers.
The only organization that would be concerned about poisoning too few customers would be one whose livelihood and existence depended on the sickening and killing of customers. Let's imagine that such an organization does exist. If customers aren't carelessly killed, the income of the organization goes down. Perhaps the organization will shrivel to the point of extinction. When millions are sickened and thousands die the organization prospers and grows.
