 Prior to 1943, these dens were legally required to close by 9 pm. However, most smokers would retire to makeshift quarters inside these dens to continue their vice till midnight. The rooms inside were lined with wooden benches. Men in pairs shared a dim lamp between them and smoked leisurely whilst lying on the benches.
