Imho, resource wise, i think it is okay for the maid to carry
the bag, as it is her job, and given it is out of camp.
consider this scenario, when NSman returns home,I would believe
most would throw their laundry to the mums/maids and out they go.
So different angle, but similiar actions leh.
SAF wise, i think the boy/guy should have carry it on his own.
but given it is not a rifle or etc, just a pinch of salt.
Do it in a discreet way not in full view.
