We conducted an observational study of customers in three different types of lunch settings: a worksite cafeteria, a fast-food restaurant, and a moderately priced restaurant, and assessed the relationship between meal duration and the number of people eating at each table (group size). Results suggest a significant positive correlation between group size and meal duration, collapsing over eating settings. Analysis of variance yielded significant main effects of both eating setting and of group size, indicating that meal durations were longest in the moderately priced restaurant and shortest in the fast-food restaurant. An interaction between group size and eating setting indicates that the magnitude of the group size effect on meal duration differed in the different situations, with the effect of group size on duration being smallest, but still significant, in the fast-food setting compared with the other two settings.
工作场所自助餐厅、快餐店和中等价位餐厅，并评估了用餐时长与每张桌子用餐人数（群体规模）之间的关系。结果表明，在不同用餐场所中，群体规模与用餐时长之间存在显著的正相关。方差分析得出用餐场所和群体规模均有显著的主效应，表明中等价位餐厅的用餐时长最长，快餐店的用餐时长最短。群体规模和用餐场所之间的交互作用表明，群体规模对用餐时长的影响程度在不同情况下有所不同，与其他两种场所相比，在快餐店中群体规模对用餐时长的影响最小，但仍然显著。
