Describe it. I'm an excellent visualizer!
I do get your sentiment. It can feel like an obligation to mentally keep a running tally of balances between frequent zappers. Then there's the feeling sometimes of, "are they zapping me less often and getting one over on me?" All over 12 cents lol.
However, when my zapper is broken on rare occasion, I am annoyed and feel impotent.
It's interesting. Overall I like it. In time I'll probably reach a point where I save up for "bigger" ones for things that count. Majority right now is just pushing pennies back and forth to the same 5 people lol
