DoorDash warns customers who don't tip that they may face a longer wait for their food orders

DoorDash is informing users of its delivery app that customers who don't tip may have to wait longer for their food orders. 

Users who enter zero as the tip amount in the DoorDash app now receive a a pop-up warning explaining that it's up to drivers, dubbed Dashers by the company, what orders they want to deliver. Drivers have discretion on what orders to accept and are more likely to prioritize customers who offer a tip ahead of delivery, DoorDash said. 

"Orders with no tip might take longer to get delivered — are you sure you want to continue? Orders that take longer to be accepted by Dashers tend to result in slower delivery." the app tells users, according to The Verge.
