Next time you tip, inform your server that it has nothing to to with their performance, you're actually just adding what they would have made if they were paid appropriately to the base price.
edit: I'm not being facetious, I have added 20% no matter what for at least 20 years. I've tipped servers that I'm pretty sure I hated.
edit: You're paying less for your meals than you would in your hypothetical ideal circumstance irt tipping, and that difference is coming out of the server's pocket. If it doesn't bother you, it doesn't bother you, but you're no freedom fighter.
Business owners are shirking their responsibility to pay a living wage. They’re also setting up a socioeconomic reality that pits customers against workers to absolve them of that responsibility.
Go ahead and keep advocating for tipping though, I’m sure you’re really making progress.
