Have you ever experienced a clawback?

If you have, you know the shock and horror that washes over you when you get that finance email in your inbox. Goes something like thsi:

Dear Shitty Rep,

Your horrendous deal fell through. The angel of a client, that you dragged through the mud, has opted-out of their contract and we let them walk away without recourse. Due to your stupidity, we want back all of the commission we paid you. You must pay it back in the next 90-days by forfiting all future commission earnigns.

Love,

Finance Gods

PS if you quit now we won't be able to get the money back, so quit, idiot.

Anyways, have you ever gone through this?
