A door must be located at or near the front of every place of business selling packaged alcoholic beverages. The back door to such place of business or storage area must be kept locked at all times except when merchandise is being received. In cases of orders or ordinances of a governing authority forbidding the locking of a back door because of a fire hazard, the Commissioner will make exceptions to this rule.
