Tipping privacy: The detrimental impact of observation on non-tip responses
研究发现减少小费隐私会损害顾客的再次光顾和口碑，因为顾客感到不那么慷慨和缺乏控制感，允许顾客修改初始小费金额可缓解这种负面影响。
• Reducing tipping privacy has damaging effects on consumers’ repatronage and WOM. • Tipping hardware, employee behaviors, and platform policies impact tip privacy. • Privacy impacts feelings of generosity and control during and after the tip process. • Tipping privacy has different effects on Repatronage/WOM and tip amounts. Digital point-of-sale platforms disrupted the norm of privacy-while-tipping. Previous research indirectly suggests that firms can increase—or at least not decrease—tips by reducing tipping privacy. The effects of tipping privacy on non-tip responses, defined as customer responses subsequent to the tip selection, including repatronage and word-of-mouth, remain unexamined. Related voluntary payment contexts (e.g., donations) suggest consumers sometimes prefer public observability and other times prefer privacy. We examine how and why tipping privacy affects non-tip responses. A field study and four controlled experiments find that diminished tipping privacy reduces non-tip responses because customers feel less generous and in control. Allowing customers to change initial tip amounts mitigates these detrimental effects. Providing insight into the inconsistent effects of privacy on tips, we find that diminished perceived control increases tip amounts, while diminished perceived generosity reduces tips. Managers adopting privacy-reducing technologies and service scripts should consider the damaging effects on non-tip responses.
