It's totally unimportant, but you'll find plenty of random people who ask you to do things for them, in most cases you just get items, but it's still something more to do. first one you find that I remember is the dancer in Castelia City Square, battle him. he's got a "Pan-" monkey. he asks you to find his partner, he's down the middle left "road" which is actually an alley. fight him, he's also got a "Pan-" monkey. he'll go to the square. I don't think you get anything out of it, but it's just something to do as a goal, find every civilian you can help out.
