arrow Moments before a driver had fatally struck a Queens delivery person on a scooter before slamming into an outdoor dining set up belonging to the Rosatoro Restaurant in Astoria, Yekaterina Tsvetkova was about to toast to a nice Thursday evening inside the eatery next to the exterior booths. As she, her boyfriend, and a friend were about to raise glasses, the driver of a 2013 Mercedes-Benz C-300 slammed into Xing Long Lin, 37, on his scooter and then plowed into the restaurant’s outdoor dining area, leaving behind a trail of carnage. Lin, an Elmhurst resident, was in the middle of a work shift delivering food for a nearby sushi restaurant.
