It's difficult without digging into the topic that these commissions exist because those kickbacks are fundamentally unjustified (and largely contested by restaurants). The current situation has caused restaurants to be more and more dependant to this revenue stream and are not in a position to negotiate.

Drove a Grubhub sales rep around. Usually between 15-30% depending on the package they picked. Which would also determine where they ranked on the site when someone searched for their cuisine. This was when they were just starting out their delivery program.

I'm down to use an alternative. All it needs is an iOS app, a website, a support line for order issues and to remove restaurants that repeatedly have issues, and secure payment methods. One app to aggregate all the restaurants that don't want to get screwed by the Ubers and Grubhubs. Since 2014 I haven't seen such an app. If one exists, please let me know, and the millions of restaurants as well. Perhaps a non-profit intermediary or collective could exist here.

I've also noticed the food prices are marked up by $1-2 on uber eats, even if doing pickup; Im not sure if its uber or the restaurant doing it, but I've verified the markup exists on multiple shops
