That's not what a tip is.
> The fact that people know that they can tip "high" then revoke the tip after delivery indicates that the purpose of this tip is understood.
If they are doing that not because of service but because they only wanted to "entice" someone to pick up the order and then renege, then they are abusing the "tip" functionality, not using it for its purpose.
Dasher should be incentivized by Doordash payment to deliver order. I also thought, as a customer, that Doordash routing was determining when Dashers pick orders up and the ordering of deliveries, and am disappointed to find out they do things this way (showing dashers tips and letting dashers prioritize higher tip orders).
