Which is it? Hint: Restaurants frequently get the answer wrong. Here is the answer from the United States Department of Labor website:
Overtime: Overtime must be paid at a rate of at least one and one-half times the employee's regular rate of pay for each hour worked in excess of 40 hours per week. Tipped employees who receive $2.13 per hour in direct wages are also subject to overtime at one and one-half times the applicable minimum wage, not one and one-half times $2.13.
Note: Maryland's minimum wage for tipped employees is $3.08.
