Either way it doesn't put her in the wrong..speculation.That isn't hearsay. Hearsay would be relying on statements made outside of the trial e.g. "My neighbour told me that they saw someone else take the food".
She can take a picture of the food outside of his place. All that will prove to a judge is that she left the food at spot at that moment in time. It will not prove that the resident took the food. She would need a photo of the handover.
