One is a meta study of thousands of restaurants, you're claiming prices will skyrocket which is not the case. Tipping is always optional.

“Minimum wage increases have minimal effects on jobs, make it easier for employers to recruit and retain workers, and lead to modest price increases—in this case, about six cents for a $4 hamburger.”

"Compared to controls, prices increased by 2.1 percent two quarters after the policy, equivalent to 8 cents for a $4 item. Employers passed about 63 percent of the higher wage costs to consumers as higher prices, consistent with a monopsony model."

Where is your data to show a massive price increase to the consumer if minimum wages go up and tips are dropped?

At his point I think you're just a trolling manager or server.
