i can't. cos the nature of my job is that there must always be 2
people at my customer's place. since today i'm not around, my
colleague is alone there and normally a replacement must be there
to cover me.
my boss called me today saying they can't find a replacement to
cover me as everyone is tied up and are prepared to get complains
from the customer.
knowing how fark up the customer are, they will sure make a lot of
noise if only one person is around.
so i can't really afford to be gone for so long. tomorrow die die
must go back.
