Kara, it seems like you aren't speaking from knowing anything about working with tips. Having 10+ years in the hospitality industry, I will weigh i why you are completely wrong and very presumptuous/arrogant for calling people dumb for not wanting the initiative to pass.
Tipped restaurant and bar employees in big cities such as D.C. make more, like way, way, way, way more than the minimum wage. If by some astronomically small chance they make less than the minimum wage, the employer will cover the difference. That's the minimum wage exception.
With this initiative, FOH employees are no required to be compensated the same minimum wage as anyone else. But here's the kicker, their employers are no longer required to let them keep their tips. In order to make up their losses from having to pay their employees 3x more their previous hourly wage (and make no mistake, it is an extremely small margin business model to begin with), the business owners can and will just tack on a mandatory service charge to their meals. Or they would have to increase their prices.
Either way, their higher hourly wages will be passed on to the customer. The level of service will decrease as, highly skilled workers will move to more lucrative cities. It's good for the lower skilled workers such as bussers and dishwashers, who will now be making the same minimum wages as the servers and bartenders. But do you really want a dishwasher to mix your drinks?
I was in DC for a few days two weeks ago and literally every fucking restaurant had a vote no on 77 sign on the window. Along with a rainbow flag and other Pride week regalia. It's mostly a very progressive city, but the people whose livelihood this initiative actually affects were universally against it.
There are some well known restaurateurs that have experimented with doing away with tips. They saw a substantial loss of qualified staff and lower earnings for their employees across the board. It's also shitty for people who grew up in a certain city and love living their and doing what they do to suddenly find themselves maki g a minimum wage (which is $12 in DC btw). So now they have to move somewhere because they can no longer pay rent/make a living.
