This incentivizes both the customer and service provider to act in everyone's best interest as the service provider improves its service to increase value, and customers are benefitting from discounts the more they use your service. Customers who have high volume are also less likely to drop in volume as they will pay more for using the service less.

They floated around, they wrapped their arms around the chamber, and they interacted with the other octopus in a much more fluid and generous way.
