Yeah, it's obvious ordering delivery is going to be expensive as shit compared to picking up, but I do think the way it's displayed is bullshit. The McNuggies aren't more expensive to the restaurant because they're getting DoorDashed. "Oh, but the app has to make money someone how and cover taxes and development and payroll, etc." That's literally what the "Service Fee" says it's there for. If that's not enough to cover it, then the service fee should be higher so people can see just how much they're being fucked in comparison. Marking up the individual items is scum tactics.
I'll get delivery twice a month, since I get some bennies from my credit card for it. I'm well aware I'm getting ripped off to be a lazy shit, though.
