For UberEats the listed prices are also different from when you order directly at the restaurant. Its not just he ridiculous service fees.

Yes, I was chatting with a local resturant and they said they have to put higher prices on Uber to cover the fees.

Doordash has the $2.99 priority optional fee, I dunno about other services.

I'm sure this isn't limited to any single company. It's just typical VC/techbro company playbook.
