A couple was considering opening a new take-away store in a Melbourne suburb, where there was an existing set of stores. To understand potential customer demand, the couple created a short survey to ask those walking past the existing stores. They conducted the survey, each morning 9 - 12 pm in the first week of December 2020. Their survey asked people their age (years), preferred take-away food, number of members in their family and distance they lived from the location (km).In January 2021, the couple opened their takeaway store in the suburb.
