There are various causes which conspire to make pretty waiter girls. They belong to three classes: First, the young girl who, but recently fallen into sin, is placed there by "her friend," which appellation more frequently than otherwise stands for "her seducer"; second, the young female who naturally seeks a position as waitress, because it pays her best, the proprietors of some saloons paying a weekly salary, in others a percentage upon the drinks sold; and third, an older kind of female who, having run the gauntlet of nearly all forms of feminine degradation, and losing most of the charms belonging to her sex, sees a chance, upon the percentages allowed by the "boss," and the overcharge squeezed from frequenters, of making a living, with a prospect of once in a while finding a man so drunk as not to have any choice in a companion for the night. To this sort of individual, all females are beautiful and the ancient and faded siren has as good a chance for patronage as her younger and more favored rival. Hence the concert saloon has its advantages for all kinds of women, as well as its uses for all kinds of men. The price of drinks in these places varies according to the tact of the pretty waiter girl, the sobriety of the customer, or the "rules of the house." In all cases, however, drinks are higher than at ordinary bars, for the musicians have to be paid, the girls to receive a percentage, as well as the proprietor to reap his harvest. Besides, the smiles of lovely women must be reckoned at something. In the Chatham street and Bowery dives, the worst and cheapest of liquors and beers are dispensed to customers. In many of these concert saloons "private rooms" have been arranged, where anyone so disposed may choose his female companion and retire to quaff a bottle of wine (?) at five dollars a bottle--a customer who indulges in such a luxury as wine being too important and consequential to associate with the common visitors. Money here as elsewhere has its worshipers.
