In-N-Out Burger has sued on-demand food delivery service DoorDash due to food handling and safety concerns, according to TMZ . A part of the filing obtained by TechCrunch explains that the food chain isn’t happy that DoorDash is using its trademarks, when it has no control over how its food is handled and how much time passes between the purchase and the delivery. Further, the delivery service’s website is using In-N-Out’s logo without permission, even if the restaurant previously asked for it to be pulled down more than once. Source: TechCrunch , TMZ
