The holders of permits issued under this Chapter shall, upon thirty (30) days' notice, produce their books and accounts for examination by audit agents authorized and designated by the Mayor and Council to determine the gross receipts. The permit holder shall be required to reimburse the City for reasonable charges connected with such audit or examination. In the event that the permit holder requests a rate increase above the maximum amount set forth in the original application for permit, the permit holder shall deposit with the Clerk a sum deemed sufficient by the Mayor and Council to pay the costs of the City's audit of the permit holder's books, accounts and records by such person designated by the Mayor and Council to give the City advice as to the merits of the proposed rate increase.
