When Lynn Staffieri, a resident of Magnolia, Delaware, saw her Amazon delivery driver running away from her house, she wondered what she just witnessed.She received the notification through her Nest doorbell, a service that provides video-capture for home-monitoring and security."I said knock three times, scream abracadabra and run very fast away," Jacob Staffieri said."I saw the Amazon lady running away from the door and I thought 'Oh, that's weird,'" Staffieri said."I didn't have the audio at first when I saw it so I didn't know what was going on."When she came home and saw the footage in full, she learned that her son was behind it. He added unique delivery instructions to the order.
