yes, you're right, what i said wasn't fully true for expediency's sake, but your statement isn't fully true either. federal minimum wage laws don't apply to tipped workers in the same way (iirc, it varies based on the state, i'm not sure).

if an employee doesn't at least make minimum wage after tips are considered, an employer is required by law to compensate an employee up to the point where they do make minimum wage. in theory.

in practice, this doesn't always happen.
