That 18% service charge on a Brickell restaurant’s check isn’t a tip for the server, a federal judge ruled in the U.S. District Court for the Southern District of Florida.

The case hinged on whether the service charge on a restaurant bill counted as a tip for the service staff at Nusr-Et Steakhouse in Brickell, who were seeking minimum wage plus overtime. The case turned on whether the service charge was the sole compensation for the service staff as dictated by federal law.
