or should i say , day cabby must learnt those correct things ,
night cabby must learnt those correct thing as well .
Eg ...Day drivers , u no need to learnt by hard where is Geylang
Lor 12 , Lor 16 and Lor 18 , & their specialties , cos day time
, not much activities going on .
Rather u must absorb as much as possible where is Philipines
Embassy , Indonesian Embassy , cos maids sometimes u picked will
need to go there .
So many need to learnt .
Vice versa , Night drivers learn where is Embassy for fuck ? But
night drivers must know what is Las Vegas , where is Zouk , where
is Stereo Lab , or where is Latitude .
night drivers must know where to find good body massage plus
"special" type ... or where to find "Thai Services" etc ....
night drivers must also know what's so special about Orchard
Tower or Prinsep Street or ParkLane ?
basically nite drivers macham part time pimp or or gui
tao............ 
but be smart also some places have "ting tong" lobangs
1...........
like hotels, spas etc.............
