So what did you do? Did you get down the bus eventually?
Personally, if i were you, I would have made a din in the bus.
Please lor, the bus driver is supposed to drive a bus, not to haunt
the passengers and make false accusations that they are cheating,
etc etc. If you are right, you MUST fight for your own rights, if
not, those haughty bus drivers will become more and more arrogant,
thinking that they can bully more people. In addition, you will get
the upper hand because the break time of those bus drivers are at
stake and they have some explanation to do should they not arrive
in the bus terminating point on time.
