It is the duty of each public weighmaster to permit any interested party to read the indications on the weighing device or on an accurately projected image of the weight indicator when a commodity is weighed. In the event the public weighmaster fails or refuses to permit an interested party to observe the weighing of a commodity at such time, the interested party shall have the right to have the commodity immediately reweighed without any additional charges.
