In January 1985, Dahmer was hired as a mixer at the Milwaukee Ambrosia Chocolate Factory, where he worked from 11 p.m to 7 a.m. six nights per week, with Saturday evenings off. Shortly after Dahmer found this employment, an incident occurred in which he was propositioned by another man while sitting reading in the West Allis Public Library. The stranger threw Dahmer a note offering to perform fellatio upon him. Although Dahmer did not respond to this proposition, the incident stirred in his mind the fantasies of control and dominance he had developed as a teenager, and he began to familiarize himself with Milwaukee's gay bars, gay bathhouses and bookstores. He is also known to have stolen a male mannequin from a store, which he briefly used for sexual stimulation, until his grandmother discovered the item stowed in a closet and demanded that he discard it.
