My fear at not tipping at literally every Square/Clover terminal (coffee shop, sandwich shop, etc) is that the employee...who almost always vigilantly watches to see if I tap on one of the unavoidable tip options...may seek revenge for me not tipping. Doing something to the food, drink, whatever.
I feel like the whole modern POS system customer UX is designed to make the act of not tipping feel so overt, miserly, and risky.
