tipping taxis

the first case of ridicule is reported in the front page of the straits times. cabby drove passenger to destination without asking his preferred route. passenger complained and got a refund. i will do that the next time if cabby forgets to ask and get my refund. this also assumes that all the passengers know which route to take. if one is not a driver, how does one know which is the best route to take? and now, if one is not frequently on the road, one would not know which route will be the most expensive given the number of gantry points to pay. things are getting more interesting by the day. an innocent passenger may just say go this way and that way thinking it will be cheaper but ended up paying more because of the gantries. and then make a complain against the taxi driver or refuses to pay. we have a really informed public who knows which route to take, better than the taxi drivers.
