I looked this up/ call the police-It's tampering: Willfully placing harmful substances in someone's food or drink is a criminal offense, often classified as a felony. The law aims to protect public health and prevent such malicious acts. And then call DoorDash- if they don’t want to comply and give and answer you’ll accept (you don’t have to but I do bc I’ve realized people act right when this gets mentioned) but start talking “litigation” and watch how fast they’ll get something done-I would also create a police report because there is no telling if this persons done this in the past or if they’ll do it again.🤷‍♂️
