There are many states where minimum wage for workers is above the federal $2.13 (actually, a bit more than half): https://www.dol.gov/agencies/whd/state/minimum-wage/tipped
This whole $2 thing is bullshit that’s carried forward if you’re the average HN reader in a coastal city. My friends who are waiters across a spectrum of restaurants (in a coastal city) probably make $50-60 an hour, and double that at the higher end places, for a job that yes, can be exhausting (but not exceptionally more so than many other low-skill jobs), and requires no specific training or degree.
