On Saturday night, Pim Techamuanvivit got a phone call at Kin Khao, one of her restaurants. A customer wanted to know why his food hadn't been delivered.

But Kin Khao doesn't do delivery or takeout. So Pim was shocked when she found out that a page and menu for her Michelin-starred restaurant appeared on Seamless, Grubhub and Yelp.

Pim's pages were eventually taken down, but she's not the only one who's experienced this. And in an era where tech companies are rushing to control the food delivery space, local chefs and restaurant owners can feel like they're losing control over their own businesses.
