We have to look at this issue from a marco
perspectives, of course, from a TD, I like you, agree that it is
done of everybody business if pax is willing to pay more for it and
get the best of it.
LTA expect a fair play on the ground, with system and laws in
place, they want everyone to abide to it, the taxis business
operators, TD and pax, and like every singapore rules and
regulations, they are very firm with it, otherwise, chaos will set
in.
Now, let take a look at what happen if LTA is to close an eye on
it, LV, boonlay, or whatever operators or even TC might want a
slice of it, because many paxs out there are willing to paid a
premium to get to where they want to be without much hustle, and
when that happen, which is happening, fares and prices will go out
of control, someone call and said, 50 pts-, then someone add
60pts..and so on.

Mo very Chim..... what... Macro Perspectives....

anyway....
As long as your cab has a
u got to "switch on" when there is a passenger in your cab
regardless whether pax is a family member or a charity transfer....
