quonset shares a report from CNN:

If you try to place an order through the DoorDash app without leaving a tip, you may get this pop-up: “Orders with no tip might take longer to get delivered — are you sure you want to continue?” The note goes on: “Dashers can pick and choose which orders they want to do. Orders that take longer to be accepted by Dashers tend to result in a slower delivery.” In other words, tip your drivers, or prepare to wait a long time for a cold meal. Customers are then given the option to add a tip, or continue without one.

The message is just a test, DoorDash spokesperson Jenn Rosenberg told CNN in an email. “This reminder screen is something that we’re currently testing to help create the best possible experience for all members of our community,” she said. “As with anything we pilot, we look forward to closely analyzing the results and feedback.” Rosenberg noted that Dashers, the people who deliver orders, are “independent contractors” who “have full freedom to accept or reject offers based on what they view as valuable and rewarding.” Tips go directly to Dashers, according to the company. So if an order comes in without a tip, they’re more likely to let it linger.
