For your info: A judgement in the Traffic Court against a taxi driver for not issuing proper receipt and overcharging.
Please read the rules (stated in the judgement) that LTA doesn't provide us. Just look at the no of rules they have in place to 'whack' TDs.
Anyway this TD deserved it, go and overcharge, but all the same it's an important lesson for all of us.
Why you say he deserve it?
I have not visited the link yet. But would! if your reason is interesting enough ( meaning summarize it here).
