In this section, “tipped employee” means an employee who is engaged in an occupation in which the employee customarily and regularly receives more than $30 each month in tips or gratuities. An employer may not require a tipped employee to reimburse the employer or pay to the employer an amount equivalent to a customer’s charge for food or beverages if the customer leaves the employer’s place of business without paying the charge for food or beverages. Subject to § 3–503 of this title, an employer may not make a deduction from the wage of a tipped employee to reimburse the employer for an amount equivalent to a customer’s charge for food or beverages if the customer leaves the employer’s place of business without paying the charge for food or beverages. Each employer shall keep posted conspicuously in a place where a tipped employee is employed a printed notice of the provisions of this section, in a form that the Commissioner requires.
