Learning
Junard R. Ocay
 It that kind of activity, I have learn how to exert more patience if you
needed to have the information that you are looking. Because we are
the one who needed the information necessary for us to know about
Bureau of Internal Revenue procedure in business, we need to wait
for the time in order for us to be accommodated.
 This kind of agency is a busy one because almost everyday you can
see a lot of people transacting to their particular concern and with this
I appreciate more the value of coming early and being on time
because if you are in a particular position, you should have learn to
appreciate the value of the effort that the single person transacting
there.
