Pricing for relief will go on forever, because it is a free
market, taxis companies and govt bodies are hands off over such
personal negiotation, as long as hirer and relief holds the
relevant licence, and are happy with each other kind of rental, be
it because of higher due nearer to each other, or higher due
to far a way or that newer taxis or that lower because of older
cabs..it is all up to both parties to strike a balance.
And then, there are no string attached, not much of a written
agreement but rather a verbal consent and accept kind of stuff, so
the right to throw keys or kick the relief out is still very much
the perogatives of both side.
As such, the rates will more or less go with the market flow,
you ask for too much, you might not find a relief or a good one, so
to speak, you want a lower rental, you might not get a good cab or
that timming will be irregular and so on.
Therefore, it is up to each and everyone to negiotate the best
of their own endeavour.
