Answer:
Primary catering refers to the preparation and service of food and beverages at the place where they are produced, such as restaurants, cafes, and fast-food outlets.
On the other hand, secondary catering involves the transport and service of food and beverages that have been prepared elsewhere, such as catering companies that deliver meals to schools, offices, and other events.
In simpler terms, primary catering is when food is prepared and served on the same premises, while secondary catering involves the transportation of food to be served elsewhere.
