Yeah, what ended up happening is that the services increase the cost of the items the customer buys by a percentage, and keeps that cost. Then they add a delivery fee that they keep, a service fee, and a tip that goes to the driver. Then they pay the driver a small portion of the fee and markup. Overall they take about 30% of the total cost of the order.

Then they treat the restaurant like a subsidiary and make them use their pickup app, and sometimes advertise a menu that the restaurant doesn’t actually offer.
They also make it difficult to give feedback on the delivery itself, since they take any negative feedback and forward it to the restaurant.

I got a credit for $50 from one of the delivery service, which got me a a normal lunch plate from one of my favorite places (usually $15), and a ~20% tip. Driver tossed the food onto my porch, making most of it spill in the bag, and their system had no way to say “the driver did a bad job”, “give me back the tip”, or anything like that. All I could do was say the restaurant messed up, which they didn’t.

Needless to say, I don’t use them even if it’s free anymore.
