The term "full service" refers to a comprehensive and complete range of services or products provided by a single source. It typically implies that the provider offers everything needed for a particular task, from start to finish, without any need for additional outside assistance or resources. In other words, it is an all-inclusive package deal that covers all aspects of what is being offered. The phrase can be used in various contexts such as in reference to hotels offering full service accommodations which include services like room service and valet parking, or in the case of a financial institution providing full service banking which includes checking accounts, savings accounts, loans, and investment options.
