On a cold, wet winter morning, the last thing you want to hear as you clamber on board the bus is a censorious mechanical voice announcing to your fellow travellers that you've incurred a penalty payment.
I knew it was going to happen. The Hop card helpdesk had warned me the previous day when I rang to complain that the on-bus card reader had gone haywire as I got off the bus.
She was not surprised. It had been happening a lot. It was a system error, and in the Kafkaesque world of Snapper travel, I'd be penalised the next day for not clocking off after the previous journey - even though the machine had refused to let me do so.
If I rang the next day, after the transaction had been transferred from the bus reader into the master computer overnight, the helpdesk would manually cancel the penalty. That was Tuesday morning. The last time I looked, mid-yesterday afternoon, as far as Snapper was concerned my last trip was on Monday evening, before the nightmare began.
On Wednesday afternoon, Auckland Transport came up with the explanation that it was an isolated error, caused by the driver of an Outer Link bus keying in the incorrect trip number. As a result, passengers had been unable to tag off, meaning an automatic penalty charge on their next trip plus a public dressing down by the machine.
