Does it matter if it is a safe assumption (the intended animal/homeless person)? You can accidentally drop chocolate, and choose not to eat it, you cant really accidentally drop sliced bread laced with rat poison can you ???
It would be nice (though cant really give someone life for killing an and or a spider), scummers I hope next time they get bitten by a dog. I've seen tons of homeless too that would be delighted with a few slices of bread albeit from the floor
