A sea of pink and green T-shirts filled the Montgomery County Council chambers in Rockville Tuesday as a couple hundred community members, primarily service workers and restaurant owners, gathered to share praise and opposition to a controversial bill that would raise the base minimum wage for tipped workers, if passed. Restaurant workers who support the legislation wore hot pink shirts with “One Fair Wage” on the front. Those in opposition wore kelly green shirts with a message of “Save Our Tips.” The Rockville chambers were split about evenly between the two sides.
