If the goal is to do away with tipping, I don’t know of another way besides banning it that will be effective.
The provinces of Ontario, Alberta and British Columbia all did away with the seperate (lesser) server wage so that all employees go by a universal minimum wage. I don’t think that changed patrons’ tipping habits one bit.
And servers are still reliant on the good will of people. Ain’t nobody with real expenses getting by with some of these minimum wages. Not with the current cost-of-living.
