A casino host is employed by a casino to deliver services to gamblers to help ensure that they become loyal patrons.
A Casino Host will usually try their best to please patrons of their casino and will do their best to fulfill any reasonable requests their clients might have. The casino host has the power to issue complimentary services (or "comps") to players. Comps can range from complimentary meals, beverages, and show (concert or theater) tickets right up to full accommodation in a hotel casino. A Casino Host will develop a relationship with every level of gambler, from first-timers playing quarter slots to high-profile multimillion-dollar gamblers (a high roller).
The casino host reports directly to the marketing managers in most casinos. The Casino Host is the member of management that has the most contact with players and patrons. The job of a Casino Host can be very competitive as they are seeking the repeat patronage of players, a common goal that is shared with competing casinos and their own Casino Hosts.
Las Vegas has a main character, Samantha Jane "Sam" Marquez, who is a casino host.
