Here in WA state, the minimum wage per hour is $15.74 (higher in some areas). Tipping culture says 20%, but that’s generally to support lower paid waitstaff in areas that can pay less than minimum wage by employers. Where/What are you tipping and what kind of service would you expect for a 20% tip?
Just because minimum wage is high, doesn’t mean it is a living wage. Here is a great breakdown of costs in Washington

With wild inflation and general CoL increases, long gone are the days of the $15/hr being livable. As far as tipping culture goes, it is fucking bullshit. Just pay your staff and increase menu prices as needed. That being said, changing the culture around tipping will take a sea change by either making minimum wage a living wage based on inflation or UBI. Or both. Not tipping because it is bullshit only hurts the people who have the most to lose.
