You can't be complaining for a bus driver doing his job can you?
He may ask to see it everytime even though he has seen it before but if management ever reviewed cctv and noticed he hadn't checked ID the driver would get the blame
It's like saying the 90yr old pensioner with two walking sticks and a happy birthday badge pinned to them would still be expected to show a concessionary pass.
You also have to remember you may recognise the same driver quite often however think of say the bus driver doing 10 laps of the X66 - how many passengers faces has he seen that day
