There are lots of different types of clients. Some use your response to their first request as a measure of your standard output. Once that is known, a difficult client might continue to demand more.

Sometimes their insecurity compels them to avoid getting screwed, by making sure they're getting everything they can out of you. Other clients, with lower expectations, might be overjoyed by the the same efforts. All clients are not equal.
