I love that we're just like "so FYI we decided this particular class of worker is okay to pay less than a living wage but to compensate if they do really good at their job, we're going to make it a social norm that people pay more than their bill costs and they keep the difference."

Wouldn't it make far more sense to just pay them a living wage and charge what that costs and be done? It's genuinely the only part of eating out that annoys me is it ends with a math quiz.
