This persuasion strategy involves asking for a large favor first and then asking for a smaller favor after the first one is denied:

Door in face

Explanation:

In psychology, the door in face technique is a method of persuasion according to which the persuader tries to convince other person to comply to a large request (which the other person will likely say no to), then, the persuader makes a significantly smaller request and then the other person is likely to say yes.

It's been observed that using this technique the other person is most likely to accept the smaller request than if the request had been presented by its own at first (without the large request first).

Therefore, the persuasion strategy that involves asking for a large favor first and then asking for a smaller favor after the first one is denied is called the door in face.
