City's Coney Island, which was filled with "ramshackle groups of wooden shanties", bars, cabarets, fleabag hotels and brothels. Huge bouncers patrolled these venues of vice and "roughly ejected anyone who violated the loose rules of decorum" by engaging in pick-pocketing, jewelry thieving, or bloody fights. During the 1890s, San Diego had a similarly rough waterfront area and red-light district called the 'Stingaree', where bouncers worked the door at brothels. Prostitutes worked at the area's 120 bawdy houses in small rooms, paying a fee to the procurer who usually was the bouncer or 'protector' of the brothel. The more expensive, higher-class brothels were called "parlour houses", and they were "run most decorously", and the "best of food and drink was served." To maintain the high-class atmosphere at these establishments, male patrons were expected to act like gentlemen; "... if any customer did or said anything out of line, he was asked to leave. A bouncer made sure he did". 20th century Bouncers in pre-World War I United States were also sometimes used as the guardians of morality. As ballroom dancing was often considered as an activity which could lead to immoral conduct if the dancers got too close, some of the more reputable venues had bouncers to remind patrons not to dance closer than nine inches to their partners. The bouncers' warnings tended to consist of light taps on the shoulder at first, and then progressed to sterner remonstrations. In the 1930s, bars in the bawdiest parts of Baltimore, Maryland docks hired bouncers to maintain order and eject aggressive patrons. The Oasis club, operated by Max Cohen, hired "...a lady bouncer by the name of Mickey Steele, a six-foot acrobat from the Pennsylvania coal fields. Mickey was always considerate of the people she bounced; first asking them where they lived and then throwing them in that general direction. She was succeeded by a character known as 'Machine-Gun Butch' who was a long-time bouncer at the club". In the Weimar Republic in the Germany of the 1920s and early 1930s, doormen protected venues from the fights caused by Nazis and other potentially violent groups (such as Communists). Such scenes were fictionalised in the movie Cabaret. Hitler surrounded himself with a number of former bouncers such as Christian Weber; the SS originated as a group designated to protect party meetings. In early Nazi Germany, some bouncers in underground jazz clubs were also hired
