When Jimmy’s was out of sight, Flynne saw something lift out of the SUV, headed back toward them. It became a small quadcopter, toting a fabbed cornstarch travel tray with a silver-foil bundle and a paper cup clipped in it. “Watch this with the bed,” Tacoma said, without looking back. Flynne turned in time to see a rectangular hatch in the bed cover sliding open. The drone matched their speed, then lowered itself through the opening. Then came right back up, minus the tray with the burrito and coffee, climbing out of sight as the hatch closed beneath it.
