Anyone claiming that GrubHub is only taking a 30% delivery fee and ignoring all of the other charges they tack on to reduce restaurants' income is simply lying.
edit: reading further, grubhub auto-opts in the restaurants into this promotion. That's scummy, but also exists due to US auto opt-in. I believe in Europe, this wouldnt fly as they need you to explicitly opt-in, not explicitly opt-out after they implicitly opt-in. Scummy, but the american way
edit2: i think the verge, incorrectly reported in late march that restaurants "must" opt-in. from the perks program T+C. "Your participation in the Perks10 Program (the “Program” formerly known as “Supper for Support”) is optional. By electing to opt in each restaurant location identified to the Program, "
so 42% for both "advertising/marketing" (grubhub is providing the order to the restaurant). and delivery. If you link to grubhub from your restaurant's website. The advertising/marketing fee is waived
