Comfort ...although their rental is the most expensive ... but
the extra cost is replaced by the effiencient MDT , so call our
on-call machine .
All taxi do have on-call machine , but it's a question of : "
How frequent customer call their hotline ? "
Comfort call is full automated .... customer like booking our
cab .
Per booking our revenue is nett $3.00 , if lucky 6 bookings per
shift , it's an extra $18 profit , although rental slightly more
expensive , like $3 more , worth it still .
Comfort also subsidised the diesel cost for cabbies , and this
point is important .
