Let's put this into layman's terms for you my feathered friend.
You told us you would sing for gold, nobody wanted to give you gold. This is because you are always asking for gold.
You were given 20,000 coins to sing Rock And Roll All Nite - Kiss.
After you were given your gold and refused to sing, I put up a hat for 15,000 and knew you would accept it.
Now the way I see it, you owe the clan 5,000 coins.
