I hate to be a contrarian but are you familiar with the origins of tipping?
During prohibition, restaurant owners couldn’t break even on food alone so they decided customers should pay the bulk of the salaries via tips.
It’s worse now that it’s become customary to tip all service providers but the original intent (as bad as it was) was just to make up for business owners who weren’t paying a living wage (or later even minimum wage)
Of course I tip waitstaff and I tip them well! Because they don’t make minimum wage, I have to but morally their employers should pay their full salary.
