In the village that I once served in there was an elder sort of like that. He was the PO. Loved to eat and you'd win his favor if you fed him. He was especially nice to those who would be able to do him favors - let him use the car, give him or his family lifts, run errands for him - you get the pic.
He was falsely humble and loved the power his position gave him: he'd use it as an excuse to pry into your and other's affairs and seemed to want to find dirt on people so he could 'beat' them in private meetings and from the platform. (Guess it made him feel more 'holy' and righteous, good about himself.) He'd pop in unannounced at people's homes - hoping, I think, to catch them 'out' or maybe get a free meal. He excused his behaviour by calling it 'caring for the flock,' showing an interest in them.
He was smug and loved to criticize other elders, find fault with them. If you were too friendly with those whom he disliked you could be sure he'd try to make you unhappy. If you were a bro. you got no 'decent' parts in the meetings, if any at all. He frustrated the hell out of one Special Pioneer elder that was sent to help out as he wasn't given any responsible parts on the meeting for weeks!
Remember those service meeting parts that were to be used just for addressing the needs of your own congregation? He'd tailor those talks to target members of the Cong. who crossed him. Small cong. You couldn't help but know who he was talking about. In one case I know of he'd been untrue (lied) about the person he targeted but I couldn't - didn't? - want to believe it: he was an elder, the PO, in good standing.... Later I found out he really had lied! From the platform too!!!
Anyway, to get back to topic, he didn't outright ask for money but did expect to rewarded materially.
