The taxi driver, however, buys fuel from a petrol station, machinery parts from a garage, meals while on duty from a food outlet and so on. Petrol stations, garages and food outlets all hire staff and produce output to serve the taxi drivers, who in turn serve customers, some of whom are tourists. The food outlet in turn engages food manufacturers, electricity companies, delivery services and many other industries to provide the necessary inputs required to prepare the snacks it sells. Similarly, many industries are involved in supplying the necessary inputs to the petrol stations and the garages. The chain effects on output and jobs started by the initial taxi service demand of the tourist comprise what is termed tourism’s indirect effects on output and employment.
