Postmates is so useful though. I think it's pretty clear in its marketing that it is a service that will go to a store or restaurant and buy the things you ask for, similar to the way Instacart works. Doordash on the other hand will sometimes do this without making clear which restaurants it has a relationship with or not. That causes all types of problems.
