I agree taxes are not hidden charges, but it does sound a little deceitful to me that doordash bundles taxes with their service fee as one line item on their checkout page.

And, I don't share the same sympathy for the doordash drivers. I was already charged a delivery fee and a service fee separately, why is it still my responsibility to make sure the drivers get paid enough and not doordash's. Besides, the idea of tip for me is that I pay extra if I am happy with the service, and now I am expected to mindlessly pre-pay a tip before knowing if the service is going to be good or not. A reason why I prefer ubereatz, its a rating system but after the delivery.
