My Delivery Rider Has Been Missing For Three Years

Synopsis

For seven days in a row, a note with the exact same words was slipped into my takeout. [Don't eat it. He's watching you.] I thought it was a prank until I checked the security footage and realized the person delivering my food every night wasn't the account holder. That delivery driver's profile had been marked missing in the system three years ago. The system said he was still making deliveries, but he wasn't alive anymore. Tonight, my phone suddenly popped up an order from three years ago, and the delivery guy was David Lane again. The doorbell rang. Should I open the door? One should never order takeout alone.
