Argentina, you wouldn’t get it 
Discussion
It's not for small bills, it's to replace coins whose melt value is far higher than the face value
I think at the airport every candy must be around 20 pesos (or more), we don’t have 20 pesos coins, so 2 candies must be 40 pesos or more I guess.
I guess it's been a few years (pre-covid) since I've been there... your currency value has changed remarkably since then (not good).
The thing that first surprised me though, was how poor quality paper your money is printed on; it almost disintegrates in your hand!
It's a truly gorgeous county, and I really can't wait to visit again! Hopefully spending bitcoin and not fiat.
Inflation was terrible these years 😢 (well, always the same) a lot of stores prefer to accept cash, offering 10% discount on price, because they want to avoid credit card interests, and people prefer to pay cash because of the discounts, and because they work in the black market, and a lot of them don’t have a credit card.
It's a crime what your leaders have done... I hope things like bitcoin and libertarian policies can return Argentina to prosperity.
