Research showed that a heavy waiter might be good for the business.
Does the weight of a server have an influence on how much food diners order in the high-involvement environment of a restaurant? If people are paying for a full meal, this has implications for consumers, restaurants, and public health. To investigate this, 497 interactions between diners and servers were observed in 60 different full-service restaurants. Diners ordered significantly more items when served by heavy wait staff with high body mass indexes compared with wait staff with low body mass indexes. Specifically, they were four times as likely to order desserts, and they ordered 17.65% more alcoholic drinks.
Luckily I work in a all-you-can-eat-buffet-restaurant, so with my BMI of around 18 I won’t be fired 🙂
