A term used to describe a comp level, usual short for "Room, Food & Beverage" or "Room and Full Board". Typically, a player is brought in on an RFB comp (rather than earning it during a trip). The RFB applies only to what a pre-determined number of people (say 2) might consume and covers only what might be charged to a casino hotel room. However, some common items, such as telephone calls and spa charges are rarely covered by RFB.
A term used to describe a comp level, similar to RFB, where "L" stands for Limited. Typically, an RFBL player will be limited to certain restaurants or certain dollar amounts (less then RFB)
