My friend went to a class, not a house. He came to learn, and then found the "bait and switch", and was frozen out. This is not an issue of selfishness, but it you choose to see it, then the rabbi who had a hidden agenda was the one who was being selfish. He wanted actions, didn't get them, and changed the rules in the middle of the game. The issue is deception. One should never be bullied into compliance and call it generosity.
