In israel its customry for students to go to the Kotel on Shabbos and get invited for meals. A couple of seminary girls went and were invited to someone and they seemed kinda poor and the piece of chicken leg seemed of poorer quality. They were guests and did not want to say anything
The family had a 3 or 4 year old daughter and while they were eating the kid somehow said that mommy would reward her for giving up her chicken leg so the orchim could eat (Or something similar basically saying the shabbos food went to the guests and not the children). The girls felt terrible they had eaten food from a hungry little girl.
