Abstract
The harmful tourist behaviour of taking a lot of food from a buffet, but not eating it all, remains under-researched. This study gains key insights into drivers of plate waste. Observational data show that: dinner buffets are worse than breakfast buffets; the latest breakfast serving time is worse than the earliest; high-end breakfast buffets are worse than budget buffets. The first meal a guest eats at a hotel and the presence of children also lead to more plate waste. Staff offer consistent and plausible explanations for these observations, resulting in a comprehensive model of drivers of plate waste. This model offers a basis for intervention development to reduce plate waste and by so doing minimise environmental damage caused by the tourism industry.
