1x7 - The Familiar of Zero

Having been concerned for the welfare of the commoners, Henrietta asks Louise and Saito to work undercover and figure out if what nobles are taking advantage of the lesser ranked commoners. Louise ends up wasting all of the money given to her for the mission on gambling in hopes of having enough to afford an expensive hotel. Refusing to ask for more money, Louise ends up working in a bar as a waitress. Unused to the brashness of a commoner's life, she is unable to earn any tips with her temper flaring all over the place. Her moment of salvation comes when a rather arrogant noble decides to enter the bar.
