Its actually inherited from portugese and spanish culture, where protestant puntuality is sort of viewd as a "slave" or servant mentality (which in protestant culture where "you" are equal with all before god is just not a thing). A nobleman is the lord of his own time and sets his own appointment, can be found in all spanish colonies and in the morher countries.

Also worth noting that Brazil was under a dictatorship at the time
