Not $50 only lah, knn come come go go with the change is
more than $70, can pay for TC rental per day leh. 
,
then what about the fuel, the time, all these are costs.
To some is $50 nia, but to many like me, is sweat and blood
money.
As for me, if pax gives $50 out of a sudden, then I sure grab it
first, see see, look look, then if geninue, then put it deep into
my ah pek's shirt big front pocket, then after that $50 is warm
warm in the pocket already, then I slowly give them the change.
One of the main characteristic of a successful businessman
is skrew and cunning, we TD must also learn to be that way, but how
much skrewed or screwed, or cunning we are, we cannot go far, but
at least, we must make sure you do not get screw back.
To be rich is to be calculatives, 4D or won money can spent
lavishly, but hard work earned money must sayang ok
