Doesn't mean the fitters have just left it. Because you have been told it's the same warning buzzer and oil leaking from it. I can safely assume you haven't driven a bus before as you would know 90% of the warning lights/buzzers make the same noise and the fluid could have literally been anything. 

As for sending buses out that "Aren't ready", ask yourself this. Would Arriva a major operator in these parts, in fact in most of Europe risk thier O License by sending defective and dangerous buses back on the road because they are need one for a run. You don't half hear some crazy notions on this forum sometimes.

Where's that like button gone? 

There's not a chance in hell they'd allow a bus to be sent out if they didn't think it was fit for service. Indeed, I'd argue whatever was the issue in the morning had been properly fixed, otherwise the vehicle surely wouldn't have been able to run any journeys in the afternoon/evening, as it would have been stuck in the depot with alarms going off...
