I just noticed whenever I tip, there will be -1 coin, + 1 star. I'm sure my rate does earn but not sure whether my coins being deducted since can't monitor without showing it at the same time on neighbor's bakery.
Question is, do we pay 1 coin to tip, every single tip? Is that mean we give 1 coin to our neighbor? So, if we have good neighbor that tip back, we actually earn 19 coins from neighbor then.
