The reason to take the job (and the justification for paying less than minimum wage) is tips. Most servers will make more than minimum wage at the end of the night after you factor in tips. Because of this, server minimum wage is different. 2.23 is minimum wage for them. It's just that it balances out. On bad nights, they could easily make less than minimum wage (after they pay bar tenders for making them drinks and bus boys, hosts, etc. a percentage of their tips), while on good nights they could make the equivalent of $15-20 an hour. But they're heavily dependent on tips either way.
