What about try to advertise your taxi for hire (with added
"great sale" like reduced booking charges etc) and
also valued added pick-up service for daily routine
customers with reduced offered pricing etc. At least, it saves
time and cost spending on looking here and there for customers in
peak hrs etc 
Taxi Driving is unlike Retail Trade.
In retail trade, they can offer sale, a reduce in margin in
order to attract quantity. They can "gamble" to see at the same
period of time uses, is there more profit to be generated thru
Sales.
Taxi, is an Exculsive Service trade, we just can't pick two
difference pax and collect 2 set of fare at the same time, so thru
Sales, it will not help to bring more profit at all, this is
the worst strategy uses in Taxi Driving.
Consumer will always think that they deserve a lower price thru
regular purchase, they do not see the Exculsive Service they
recieved. That why, it is the Taxi Driver duty to educate the
commuter.
They are receiving an Exculsive Service, time is taken even
before the trip starts, and usually time is also taken after the
journey. They have a uniform fares system to protect their
interest, do not ask for further discount.
Can your Boss pay you lesser when they have regular Overtime for
you?
