As a general rule, the minimum wage does not apply to "tipped" jobs.

"The American federal government requires a wage of at least $2.13 per hour be paid to employees that receive at least $30 per month in tips. If wages and tips do not equal the federal minimum wage of $7.25 per hour during any pay period, the employer is required to increase cash wages to compensate. As of May 2012, the average hourly wage – including tips – for a restaurant employee in the United States that received tip income was $11.82."
