Sexual advances
Sexual advances were any unwanted sexual behavior that would make someone feel upset, scared, offended or humiliated, or was meant to make them feel that way.
In 2369, a newly employed Sarda rebuffed Quark's sexual advances, telling him that although she'd wear her dabo girl costume and entertain his patrons, he could "keep his Ferengi knuckles to himself." She related this conversation to Benjamin Sisko, noting that Quark claimed pleasing him was part of her employment agreement. (DS9: "Captive Pursuit")
