I mean, it shouldn’t be that expensive. Where I live basically every pizza and fast food place used to offer free delivery. Nowadays because of delivery services this has died out a bit, but it still exits, yet ordering through the delivery services is way more expensive.
I honestly don’t even get it, because for a long time the delivery services were operating at a loss, not even sure if most of them are in the plus even now, yet they should be more efficient than every fast food place having its own drivers.
This is my personal take. As long as you’re careful and thoughtful whenever using them, they can be extremely useful.
