You break it, you buy it.

Ive been told "i feel so bad" too many times, I dont care what you feel like, you break it, you buy it.

I give them the choice though, they can buy me a sack that costs what they owe, hand me the cash, or buy me a new peice of equal or greater value.

I have the same rule at parties at my house where I bring out a peice. You break this, you will buy it before you leave this house, or someone will be taking flesh for money before you can walk out that door.
