The holder of a Class A or Class D license or an employee of the license holder may deliver alcoholic beverages only within the county. An employee making a delivery shall meet the age requirements of § 23–1902 of this subtitle. The deliverer and individual receiving the delivery shall, at the time of delivery, endorse a delivery form that the Board approves, certifying that: the individual receiving the delivery claimed to be at least 21 years old and the claim was supported by documentary evidence; the individual receiving the delivery knew that it is a criminal offense for alcoholic beverages to be given to an individual under the age of 21 years; and the deliverer examined the recipient’s identification. A license holder or an employee of a license holder may not make a retail delivery of alcoholic beverages unless the purchaser: or another individual at least 21 years old designated by the purchaser, is physically present to receive the alcoholic beverages at the time and place of delivery; and pays for the purchase at the time of the order.
