You jokingly say you can do this or that and would help them after success
Behind the curtain they make sure you can do what you joked about being able to do
Then you are required by 'contract' honor to deliver what you spoke of initially
They cheat to provide their side of the contract
You never see them cheat so you continue to uphold your side.
They will even cheat to make you think you owe them more than the initial contract
They will sobbatage the operation blaming the failure on you.
They will steal the product saying you failed to protect it.
They will find a way to make you submit to their system.
