It's insane how it takes advantage of good people who feel like they're doing something wrong for hitting "no tip" in settings where nobody was asked to tip just 5-10 years ago.
On the other hand, lots of people have the liberating experience of discovering that "no tip" is a sensible default to press, and from then on we're out of the tipping game. Bots don't guilt trip me anymore, hooray!
Flip the script, you're a greedy ASSHOLE for asking people to tip in this economy! Now it becomes easier to hit 0 tip. Even try negative tip, some devices allow this bug.
