Said "cover charge" shall not be collected in advance of gaining entrance to the licensed premises, and can only be charged upon a written or printed receipt, permanently recorded and numbered seriatim, presented to each individual customer or group of customers. Records of such receipts shall be kept by the licensee for a period not less than two years. For the purposes of 204 CMR 2.00, the term "cover charge" shall include all admission fees or admission charges, except that the sign required to be posted under M.G.L. c. 140, § 183D shall, in the case of an admission fee or charge, be posted on the outside of the licensed premises.

Said minimum charge shall not be collected in advance of gaining entrance to licensed premises and can only be charged upon a written or printed receipt permanently recorded and numbered seriatim, presented to each individual customer or group of customers. No licensee shall impose a minimum charge for food and/or non-alcoholic beverages upon any customer who incurs charges for alcoholic beverages equal to or greater than the posted minimum charge for food and/or non-alcoholic beverages.
