OK, since you opened the "tip" conversation...
I pay a flat fee for delivery through a service like Doordash, GrubHub or whatever. The way I see it, the effort that goes into picking up a meal at, say Chick-fil-A, and delivering it to my home is the same if the meal is $10 or $100.
At a restaurant, that's different because the tip goes to the establishment, not the driver who has no stake in the place. If I tip more, it doesn't help the establishment, and if I tip less, it doesn't hurt.
