See Part I
French maids are often depicted wearing extremely high heels or bound, what (logically thinking) would affect their ability to perform their duties. In some cases high heels do help (squatting, for example, is easier if you are wearing heels), but bondage never helps much (only one exception comes to my mind – a proper gag decreases the amount of noise).
If maids do not perform (how can you perform if your hands are bound?) they are punished. The punishment usually includes more bondage and tight fetish clothes (corsets, latex, hoods), what further diminishes the maids performance.
