A disgruntled DoorDash customer is suing the on-demand food delivery service following reports that the company pocketed tips consumers believed were intended for their couriers.

A Brooklyn man named Alan Arkin filed his federal court class action in New York’s Eastern District Monday, just a week after a New York Times article reported that tips entered via the app were not going to the delivery people, but were instead being sent in whole or in part to the company itself to offset other business costs.

Arkin’s suit blasts DoorDash Inc. for “materially false and misleading” tipping representations on it app, which the court papers called “likely to deceive the public.”

“No reasonable person would enter a tip on that app knowing that what they’re doing is going to a multibillion-dollar tech company,” he said. “It’s basically a way to make a multibilllion-dollar tech company even richer.”

DoorDash Inc. did not immediately respond to a request for comment regarding the suit but announced a policy change in the wake of the Times report.

“We’re changing our model- the new model will ensure that Dashers’ [delivery workers’] earnings will increase by the exact amount a customer tips on every order,” Chief Executive Tony Xu Tweeted on July 23.
