The Brazilian coffee vendor³

I was in Brazil from 21 May to 1 June [1981]. One day, in Rio de Janeiro, we went to a coffee shop where it said that a cup of coffee was fifteen cruzeiros. We gave the man twenty. But instead of giving us change, the man asked for another twenty.

Alo got mad at him. When our bus driver came, he said to the man, “How can you ask for more than what it says?” Finally, the man returned five cruzeiros as our change.
