Which of the following is NOT a type of food service style?

The correct choice is "C," as medium service is not recognized as a standard food service style within the hospitality industry. In food service, various established styles include quick service, buffet service, and full service, each with distinct characteristics and operational procedures.

Quick service refers to fast-food establishments where the focus is on delivering food quickly and efficiently, typically with limited table service. Buffet service allows guests to serve themselves from a variety of dishes arranged on a table or counter, promoting a casual dining experience. Full service involves waitstaff who take orders, serve food, and provide a more personalized dining experience.

The classification of service styles is crucial in the hospitality field, as it defines operational approaches and customer interactions. Medium service does not fit into this established framework, making it the appropriate answer to the question posed.
