The much questioned practice of admitting minors with adult strangers to theatres came up for a test before Recorder Pickersgill at 7 o’clock last night, when Morris Streiff was fined $15 for admitting six little boys to his motion picture theatre at 189 Hall avenue. The law permits that children under age may be admitted to theatres when accompanied by “parent, guardian or adult friend,” but Recorder Pickersgill contends Streiff did not have the right to permit a man to take in six boys whom he met outside of the amusement place, even as an adult friend.
