Some prostitutes walk the streets looking for customers. They are usually called "streetwalkers" and are the most noticeable type of prostitutes. Others work in bars and nightclubs. Others may work at a building called a brothel. Other prostitutes may work from their homes or from an apartment rented for the purpose, and have their clients (customers) contact them by phone or on the internet. Some prostitutes may have a boss (a person they work for and who they may give part of the money they make to), who may be called a "madame" (if they are a woman) or a "pimp" (if they are a man).
