The payee signs the affidavit and delivers it to your customer, demanding payment. Your customer makes claim for wrongful payment against your bank, and your bank in turn makes a claim under transfer and presentment warranties against the depositary bank. The depositary bank, if it can, charges its depositor. If it cannot, it eats the liability.
