Am not surprised Redcar have issues with their buses. I was waiting for an X4 the other day, after a breakdown a replacement bus was sent out to Redcar Clock.
The doors on the new bus wouldn't close, so the driver and two other members of staff were kicking, pulling and tugging at the floor and the door itself, and probably made the fault much worse than what it was to start with. Needless to say, that bus also had to be sent back to the yard.
But their actions in front of a large number of passengers didn't look good.
