Implications of restaurant tipping for employers and staff were discussed by Prof. Michael von Massow, Food, Agricultural and Resource Economics, in a Canadian Press interview Dec. 28. The story, which ran nationally, including for CTV News and the Toronto Star, examined how rising labour costs and decreasing profit margins affect tipping practices. As some restaurants eliminate tipping, customer response has been mixed, said von Massow, who also discussed the topic on AM 640. He studies restaurant revenue management and food value chains.
