While I understand that this is dependent on the player, I'd say Commander Shepard from "Mass Effect," the way I play him, he'd likely insult me for not helping him or paying him simply for being there, and then proceed to threaten me and beat the snot out of me until he found out I didn't have any "credits" or whatever they use for money and then finally shoot me with incendiary rounds.
Of course, the way I play him, Commander Shepard probably wouldn't be invited to the party.
But that wouldn't stop him.
