List and explain four types of catering establishmen.

Four types of catering establishment

1. Commercial (profit-making) catering: establishments whose main aim is to make profit by selling food and drink, for example hotels, restaurants, fast-food outlets and cafes. They serve the general public and price meals to earn income.
2. Welfare (non-profit) catering: establishments that provide food as a service rather than for profit, such as hospitals, schools, prisons and the armed forces. The aim is to feed a captive group at low or subsidised cost.
3. Industrial (staff) catering: the provision of meals to workers in factories, offices and business houses, often at a subsidised price to keep the workforce well fed and productive.
4. Transport catering: the provision of food and drink to travellers on the move, for example on aircraft (flight catering), trains, ships and at airports and bus terminals.

Institutional and outdoor (event) catering are further examples.
