They usually separate out the DAA villains, that isn't evident in the analysis reported. This is a weird one... the penalty seems to have nothing to do with the complaint:
Complaint: “Requested a taxi to go to the airport [that was] able to accept credit cards, the driver agreed and accepted the service. Once we got to the airport the payment terminal did not work, therefore I had to go into the terminal, got the fare and paid in cash.
Outcome: Fixed Payment Notice – Failure to print and offer a receipt.
