I can’t make it any simpler.
Easiest way I explain to dipshits why they have to tip me is this: The fees are what you pay DoorDash and the restaurant to make your order. DoorDash gets a fee for letting you use their app, the restaurant makes a piece for letting DoorDash in their restaurant. THE TIP is what you PAY ME to go get your food in MY car and bring it to you.
If your food sits and doesn’t get picked up, it’s because you paid for everything but the actual delivery. The tip IS the delivery fee.
Anyway DoorDash is ass. They can suck an egg.
