I sincerely apologize for another tipping post

Got into an argument with someone about tipping and looking for other opinions. I come from a state that pays wait staff like $3 an hour. So, 20-25% tips are immensely important to their income and are non-negotiable, even if they do a poor job. I move here for school and find out that the minimum wage, even for wait staff, is $20.67 an hour. I was like “damn, I don’t need to tip anymore” and then a friend starting ripping me to shreds about how I still need to tip wait staff cause the cost of living crisis is so high. But by that logic I should go out of my way to tip everyone who makes minimum wage here, not just wait staff? And should I start tipping the wait staff back home 75% now?? It just doesn’t make sense. I have a job as a cashier at a grocery store and I make minimum wage, should yall tip me because I bagged your groceries and I also, like the waiters in the area, am struggling with the cost of living? I can see arguments for like 5% especially for smaller businesses to help offset costs but still.

I know you probably get a lot of posts about tipping but I haven’t seen any specifically addressing this logical disjunction of tipping 20% here (where the min wage is $20.67) as well as in other states (where the min wage for wait staff is $3)

EDIT: So, I found online that the average hourly wage INCLUDING tips for a server where I come from (Wisconsin) is $14/hour. And I’m being told by some people here that I should still tip a server in Seattle, who makes $20.67/hour, the same as I’d tip a server back home because the cost of living crisis is so high. Well, Madison, the capital of Wisconsin, has a 22.8% lower cost of living than Seattle. So, if we adjust the numbers for cost of living, the Seattle server making base $20.67/hour here has about the same buying power as $15.96/hour in Madison. This is more buying power than the average Wisconsin server and I haven’t even factored in tips for the average Seattle server. If ya’ll expect me to tip 20% here and claim I am morally wrong if I don’t, you best be tipping like 50% in my neck of the woods
