We don't have it in Serbia, but I've seen cash registers abroad (in stores and at gas stations), which have a "funnel" into which you pour coins and it counts them out, takes the amount of the bill. a great thing to reduce the crowd and get rid of change quickly.
I also had one such piggy bank, I used to put 1e coin in it, every time I cursed - that was my wife's punishment.
You probably know, to us, swearing is like "good day" 😆
And at the end of the year, we went on a trip to a nearby town with that money.
The trip was not cheap... tolls, fuel, coffee, lunch, cakes, bar... So imagine how many swear words I uttered during that year 😅
