When they first meet, Mr. Bubis immediately calls Benno von Archimboldi out over his weird name.
The editors at the Bubis's publishing house frequently get together over drinks to compare and ridicule their clients' mistakes.
It takes Archimboldi a while to find someone who owns a typewriter who also don't know he's Hans Reiter, but Mr. Bubis eventually gives him a fancy one as a gift to further cement their business relationship. Archimboldi is surprised and thankful, and keeps it for decades...until he learns how to use a computer. Then he throws the typewriter off a cliff.
