The invisible upgrade nobody asked for
A $64 group DoorDash order. Four friends. Then the receipt breakdown: $5.99 delivery fee, $9.60 service fee, and a $2.99 “Priority Delivery” charge nobody remembers selecting. That $2.99 sounds trivial until you realize DoorDash often pre-selects it by default, requiring users to actively opt out. Gordon Haskett Research Advisors found in their 2024 consumer survey that 67% of delivery app users don’t notice when priority delivery is pre-selected at checkout.
Now someone in your group is paying for faster delivery that everyone benefits from equally — but that only one person (probably) selected. This is the fairness problem that behavioral economists have studied for decades, and it plays out in delivery apps every night.
The fairness question: If one person upgrades delivery speed and the whole group benefits, should everyone split the fee equally? Or should the person who clicked “Priority” pay for it alone?
