Our employees are advised to open all doors at every stop. As they have been advised differently for many years (especially during the colder seasons), the new instructions need to further sink in. So if a driver accidently forgets opening all doors at your stop, it’s not with ill intention but out of habit. We do keep reminding them about it as well.
Some buses however cannot open the rear door automatically due to technical reasons. Therefore we recommend using the middle door for exiting the bus.
