Want candy?

Just something random in mind.



Remember not long ago when in supermarkets, customers never get the small change in coins instead the checkout staff will give us candies in return? Ever thought why?
If you think because there's not enough change to give since we only have even amount for Rupiahs available, think again.

What about countries using "cent". They round them up so they get to the nearest smallest currency available in their country. Why don't we round up every sum to the nearest smallest amount we have in Rupiah.

Although I do realized the logic behind it. Since sadly enough, Indonesia doesn't have singles in Rupiah. Hence for every tenths Rupiah, we get candies. The accumulated tenths shall be the 'tip' we voluntarily give to retailers.

I don't mind the extra tip for few tenths Rupiah.
But I do wonder though, Why Candy?
When did it start? Candy in replacement for small change.
Are there any other countries that giveaway candy for change like we do?


edit:
Supermarkets have round up the amount and don't give us candy in return.
but I yet to get the answer to why they did what they did.
