Why is Mr. Ampandahalf paying the same connection fee as Mr. Wunetty?

… because consumption and service connectivity aren’t the same? Consumption and connectivity are two different line items on the bill representing different costs associated with the service.The high consumer will pay more on the quantity used, and possibly at a higher a per unit basis if it exceeds expected values.

From your hypothetical, no one is noted as having a different service hookup, so they’re paying for the same service hookup. What part of that are you struggling to grok?
