Merc Cabs at that time , they don't service local customers ,
they "fish" for Ang-Mos ......
Why don't service local customers ? Same what ? Still taxi ... u
may asked !
$$$ different la ....
Local people have to go by meter ..... where got "meat" ? From
Clarke to Boat Quay , meter $4.00 , ang-mo $15 for one short trip
like that .
Ang-Mo tourist pay and say "Thank-You very much " , local pay and
complaint to LTA , and write to St Forum the next day ! 
Ang-Mo they go by "per-trip" - $15 to $35 per trip , depending on
distance !
Locals never say "YES" to per trip , locals go by meter , even if
they can afford $35 , they will complaint later .
