Reminds me of a more recent parking lot error. I have a parking card with attached account, and credit card for automatic payments. I also had a specific car and it's plate attached so I didn't have to tap the card.

I had to cancel the credit card so automatic payments decline, and I don't always drive the same car in which case I have to tap the parking card.

The result of all this:

When I leave the parking lot in a different car after paying manually at the gate, the message displayed is "Payment Declined: Exit permitted"
