What does it mean for a friend to come to your house and ask for a handful of rice?

This situation has also encountered this phenomenon in life. Some people come to your house and ask for a handful of rice or something. I think because they are loyal, which daxian might I go to? They believe in superstition so much that someone pointed out to her that they all have to work hard because only by doing so can disaster be avoided. I will go, because in real life, we should not believe these superstitious elements.
