      He gets woken up by the wakeyuppy-wakeyupperer, who in turn is woken up by the wakeyupper-wakeyupper-wakeyupperer.

      Basically, at least one person had to be awake at any given moment or society would collapse. It happened once and they didn’t recover for hundreds of years, that’s why they called it “The Dark Ages”.

      Cities which had someone blow a horn to wake everyone up would also have watchmen walking the city at night. Presumably, they would wake the next person up when their shift ended so that someone is awake at all times.
