"Maf, what's the deal with the buses? You can only pay for them in coins but nobody gives us any change."

"Ah, porque voces nao estao a ver. If you've got coins here you're king. There are almost no coins left. They realised the metals the coins are made of are more valuable than the coin itself, so a lot of people melt the coins and sell the metal. You can get a card though, for bus rides called the Monadero."

I have seen the future and will be building myself a foundry in the basement back home.
