I mean it's not an individual act here, it's starting to look like collective action. A mass boycott of tipping would force a crisis where workers walk out en masse. Euros are giving Yanks the push they need to build on this, with unions, a collective organization, strike funds. This is the only path towards tipping abolition, a relic of class oppression and a mechanism by which capitalists shift wage costs onto consumers, esp disgusting when we know attractive or white servers often receive more than equally skilled counterparts, deepening racial and gender pay gaps and fosters a power imbalance that enables harassment: 74% of female servers in the U.S. have experienced sexual harassment, often tolerated because their income depends on pleasing the customer.
