Some comment have given a somewhat correct reply:

Some of the maid where indeed expected to also do "night duties" if asked. It was not a racial power stuff. It's was more a problem with a sort of "cultural prostitution" witch was everywhere in Ethiopia. The maids where still primary maids and not prostitute, and to be fair, the same problem also did exist in Europe at the time of Agatha Christie (How many European maid had become pregnant and then fired ?).

I thinks than it's now worst than in the 90's because Ethiopia had sadly become a tourist sex place since then. See https://en.wikipedia.org/wiki/Prostitution_in_Ethiopia
