it's human nature.
we always want to earn more money from others, employee always want
more from towkay, business man always want to earn more from
customers.
we also always want other to earn less from ourselves, towkays want
to pay less to employees, customer want to cut down price for wat
they purchased, it's all human nature.
when u are the the one giving, u want to give less, when u are
getting want other give, u want them to give more.
