What does K. believe is the reason that Hans and his family never received favors from Klamm?

K. believes that the reason Hans and his family never received favors from Klamm is that they did not ask for any. He believes that Hans married his wife, hoping to gain favors from Klamm, and that Hans' uncle leased his inn at a good price to the young couple for the same reason. However, the two never asked Klamm for anything and so never received anything.
