I've tapped out of tipping culture for multiple reasons.

1. I don't tip at fast food joints because all you did was the bare minimum. Tipping is supposed to be rewarding for extra service. All you did was take my order and ask if I wanted fries with that.
2. Prices are going up, so more of the amount I would have expected to pay is going to the base meal. For regular food, I try to tip so the final price is around $15 or $20. I don't want to pay $30 for a burger and fries
3. I've seen what tipping culture looks like when it gets out of hand. Go to the Hotel Zone in Mexico, and you'll see what I mean. Nothing is genuine, everything is about milking the tourists. I was pretty disappointed by the end of the trip. Would not recommend.
4. The base % is going up to try and milk customers, so I'm putting in the effort to counter that bullshit by picking no tip.
5. Sometimes the tip doesn't even go to the workers; Sometimes it goes to the owner. How can I tell?

Edit: I should add that there are times when I do tip, and it's when good service beyond base expectations was provided. Like if I asked for recommendations and it wasn't just the most expensive item on the menu, they were pretty prompt about taking my order, and/or it's busy / during holiday season
