The crazy thing is with all those fees, service charges, and markups they are still just barely contribution margin profitable. Amazon Prime Now / Restaurants guarantees a delivery driver a certain wage (say $XX/hr, depends on market). However what that really means is while your tip is technically going to the driver, until they exceed $XX/hr, you're just saving Amazon from having to pay them instead. I still tip, but my generosity went down when I realized that most of my tip is really just a handout to Amazon.
