No person shall deliver or distribute motor fuel within the County of Suffolk if the price per gallon of the motor fuel that is being delivered or distributed has been increased more than once in any calendar day; provided, however, that no person shall be subject to any fine nor suspension or revocation of his/her license for a violation of this section if said person can provide documentation, in a form acceptable to the Director of the Office of Consumer Affairs, evincing that the price per gallon of motor fuel was increased to said person during the course of the calendar day in question, thereby requiring said person to increase the price per gallon of motor fuel to be distributed to a motor fuel operator in order for said person to pay for the associated increase in cost, provided further that the increased price per gallon does not exceed the increased amount that was charged to the motor fuel distributor.
