It may be, Federal Law is more specific on tipping, allocation, role definitions in the restaurant industry, but not well expanded to define other industries. State law can further regulate . In spirit, a tip is an independant transaction between 2 parties and should be accounted as one. You must pay min rate for position (2.xx+?) and employee must make above fed/state min wage with tips once accounted, you must increase your compensation to make up a defecit between wage + tips vs min wage. You cannot pay below a certain wage regardless of tip amount, or maybe that's only in specified roles. I'm not sure.
