something similar happened to me.. i just went out for sushi and was walking back to the skytrain station when i saw this homeless person. i asked him if he wanted it and he asked what it was. i told him it was sushi and he said he didn't like it (okay i know some people don't like raw fish, but if you're starving you can just eat the rice). anyways his buddy or another homeless person overheard and was like, "i'll take it!" so he took it and ate it...

i personally don't give homeless people money. i would rather buy them something. i kind of get annoyed when you do something for them but they ask for more....
