A Reddit post by a Toronto-based server has sparked a heated debate about tipping culture in North America, where many waitstaff reportedly view tips below 20% as insulting. The conversation was ignited by a diner who recounted a humiliating experience from 2019, where he left a 15% tip and overheard a waitress mockingly refer to him as 'Mr Cheap.' In response, he confronted the manager and had his tip removed, ultimately receiving a free meal card as compensation. This incident has led him to avoid dining out altogether, reflecting a broader frustration among customers who feel that tipping has shifted from a voluntary act of appreciation to an expected obligation. Many Reddit users expressed their annoyance over the increasing pressure to tip higher amounts, while some defended service workers who rely on tips for income. This dialogue highlights a growing disconnect between diners and waitstaff, raising questions about the evolving nature of gratitude in the service industry.
