Is there an English idiom meaning "after they get what they want" in the following dialog:
A: Mike was much friendlier when he was a low-ranking officer. He doesn't even say hi to his old friends these days.
B: Well, yeah. He used to need us but now that he's a high-ranking officer ...
A: Right. People tend to forget about you after they get what they want (when they don't need you anymore)
