Wouldn't it be the other way around? The beneficiary is the one who is supposed to benefit from the benefactor.
I think one of my friendships is like this right now. There's a friend who seems to think i'm really cool and wants to be besties, but she kind of irritates me, although we do resonate on some things. It does in fact feel like she has some alterior motive in seeking friendship with me because she seems so overly motivated to get in good graces with me.
