I agree that tipping is stupid. Tipping incentivizes me to spend less and eat at restaraunts less, because I only want to spend a dollar tipping, at most, and so seek to spend around ten dollars, at most.
The only reason I tip at all is because some restaraunts will remember me and you tip or get to wonder if they spit in your food. What a wonderful system.
I tip nowhere else and, since I'm not remembered, I face no negative consequences of this.
