“He probably makes $12/hour...”
On what planet??? The federal minimum wage for restaurant servers is $2.45/hr plus tips. Since he was new, it’s unlikely he has cultivated a group of regulars that keep him in tips that would get him up to making that much. My daughter was an IHOP server & server trainer in college and probably made that much but it was after getting the trainer position plus being at that location long enough to get a better shift with a group of regulars she served.
After dividing her weekly pay by hours worked, how much did your daughter make?
