If you want a big favor from a person and you are not in the good books of that person, ask a small favor from him. This will eventually place you from his bad bucket to good bucket.
For r.g, You want financial help, so you approach him and ask him some water and have a small chat. Eventually, you will land in his good bucket. Which in turn will help you to get your work done.
This is called the Benjamin Franklin effect.
