taxi

the whole reseraching on taxi. my mind going nuts.
who's the CEO of comfort?
managing director of premier taxis?
their address?
how's their organizational chart like?

and do you know there's something called the taxi services?
they aren't those specific to comfort, citycab, or silver cab.
dover taxi service, lakeview radio taxi service, etc.

they have a few cabs to radio to through their walkie talkie.
cabs from comfort, city, premier, smrt.
but the thing that i can't figure out is... there are already services from comfort, citycab, etc to book their own cabs. why the need for these other services? i don't understand. why? how they earn money? take from individual taxi companies? they are sponsored by some government party? how?

the learning stage is always so bumpy.
