The necessary counterpart to the prostitute is her customer: she is the concrete answer to his demand. There are prostitutes at different economic levels, because their customers are derived from all social classes. The careless, unkempt woman at the bottom is adjusted to the requirements of the least exacting; a somewhat better type meets the demands of men of moderate means; the showy woman at the top corresponds to the fastidiousness of the spendthrift. The customers found in the fifty-cent vice resorts already described are usually longshoremen, truck drivers, street cleaners, coal heavers, soldiers and sailors, recently landed immigrants of low moral standards, and laborers of all kinds. Their treatment of the women is not infrequently brutal,--usually perhaps in consequence of intoxication. To one- and two-dollar houses resort men and boys who earn ten, twenty, twenty-five or more dollars per week. They are proprietors of small business enterprises, clerks, bookkeepers, bartenders, barbers, tailors, waiters, soldiers, sailors, messengers in banks, members of social and political clubs or of benefit organizations. Saturday and Sunday are the popular nights with men of this type. The owners and madames provide extra "goods" to "take care of the trade" on such occasions. This fact was brought out many times during the investigation as the workers went from one house to the other counting the inmates. A house that early in the week contained only ten or twelve inmates would on Saturday and Sunday have its numbers increased to fifteen and twenty-five. This was especially true in resorts like those on Sixth Avenue.[178] I have in mind one prominent organization[179] whose members are regular customers in houses of this grade. Many of the rank and file are themselves owners and pimps, who joined the club in order to advertise their houses and women to their associates. Another organization[180] of similar character has a membership of about 500 young men whose ages range from twenty-one to thirty. They are fond of attending boxing contests, wrestling bouts, athletic meets and public dances. After such exhibitions or "affairs" they go in groups of five or ten to the houses, spending long hours in promiscuous orgies. Owners make a specialty of catering to clubs of this character. When they give public balls, "rackets," "chowder parties," or other outings, the madames, buying tickets liberally, attend with their best looking inmates or with runners to drum up trade. After the ball or outing is over, groups of men and boys follow them back to their quarters.
