The Left seems to really hate tipping, where what you earn is directly related (more or less) to how well you do your job.
I have met waiters at upscale restaurants who raised families on tips. Now the Left wants them to go to minimum wage?
Oh, well, they’ll see what happens to the service at their toney DC hotspots...
What this is really all about is leveling the playing field so the cute hottie with social skills doesn’t make more in tips than the fat tattooed lesbian with gauged ears, facial piercings and green butch hair.
Create “science” to advance the agenda.
