A waiter at a restaurant had numerous duties in addition to serving customers. He brewed tea and coffee; cut, arranged, and stocked lemons and limes; and cleaned the soft drink dispensers, replaced soft drink syrups, and stocked ice. The waiter was also assigned a variety of other cleaning duties, such as wiping tables, taking out trash, scrubbing walls when the restaurant was slow, sweeping floors, and cleaning restrooms. These various activities consumed LESS THAN 20 percent of the waiter’s working hours in a typical week. The restaurant took a tip credit for all of the waiter’s work hours, including the time he spent on duties that did not generate tips. The waiter sued. Did the restaurant violate the FLSA? Why or why not? (See Schaefer v. Walker Bros. Enters., 829 F.3d 551 (7^th Cir. 2016). NB:
