i think salary is also base on per block minimum people subcri
to the newspaper,
let say each column minus ground floor till top floor, average
is 26 level, so average resident subcri, is average 12 house
hold,
you need to walk down from level 26 till you reach ground floor,
some more has to remember which house is your client, which house
is not, carry all 12 sets walking down.
if the block has 6 columns, that mean u need to walk down 6
times, if 4 blocks. mean you need walk down 24 times
