I’m no fan of AI, but this doesn’t sound like an AI problem. They switched to using delivery contractors instead of employees to put more of the risk and cost on the delivery drivers. The payment structure to those delivery drivers is not really affected by Pizza Hut’s customer satisfaction, just the number of deliveries they make and tip amount on those deliveries. So the drivers bundle orders and ignore low tip orders.

Pizza Hut can have the lower costs of contractors or the increased quality control of employees and they chose the lower costs.
