As a customer, please just leave well enough alone. I'd really prefer to just leave a tip if I'm going to be gently shamed into leaving reviews to make sure your employees somehow get the wages they were led to believe they would earn.

I would go a bit out of my way to frequent any non-tipping coffee shop/restaurant. And I'm quite happy to pay a higher price in the menu items to reflect the fact that the business isn't shifting some of their payroll burden to me in lieu of realistic pricing.
