On August 20, 2019, "Vox" released an article titled "DoorDash is still pocketing workers' tips, almost a month after it promised to stop". On August 22, 2019, DoorDash announced an update to the tipping policy and promised to "roll it out to all Dashers next month" (that is, sometime in September 2019). In April 2020, a group of New Yorkers sued DoorDash, GrubHub, Postmates, and Uber Eats, accusing them of using their market power monopolistically by only listing restaurants on their apps if the restaurant owners signed contracts which include clauses that require prices be the same for dine-in customers as for customers receiving delivery. The plaintiffs state that this arrangement increases the cost for dine-in customers, as they are required to subsidize the cost of delivery; and that the apps charge “exorbitant” fees, which range from 13% to 40% of revenue, while the average restaurant’s profit ranges from 3% to 9% of revenue. The lawsuit seeks triple damages, including for overcharges, since April 14, 2016 for dine-in and delivery customers in the United States at restaurants using the defendants’ delivery apps. The case is filed in the federal U.S. District Court, Southern District of New York as Davitashvili v GrubHub Inc., 20-cv-3000.
