Ya I used to always tip cash but stopped all food delivery entirely ~5yr ago. By turning food delivery into a live auction everybody loses except the company running the service. Drivers compete against eachother accepting the absolute lowest fees while customers need to play the game of choosing an appropriate tip for a prompt delivery while also ideally not shorting the employee who ultimately accepts the order. But since to accept the order they need to compete with other drivers it’s naturally going to lead to them accepting lower prices, allowing the delivery company to pocket the difference. Not a good system.
