The issue is that I have to trust the proprietor. In my locale it has become common for restaurants to add ‘health & wellness’ surcharges which began as charity/Covid response and of course never went away.

It is almost never the case that the restaurant provides any of this to their employees and there is no transparency involved.

I honestly see it as a scam to charge higher prices without itemizing properly on the menu.

Even if you highlight the wage disparity in signage, I would have no way of knowing whether the information is accurate or just another piece of propaganda.
