The problem here is that workers now want to be "paid properly" (what ever that means) and still get tips.
There have been restaurants have tried non-tipping models, consumers and staff both hate it. First the highly productive staff often make less under that model (where poor performers make more), consumers hate it because the menu prices increase, and you end up with McD's level customer service where drinks are never refilled, and service overall degrades.
