I remember something similar (but humourously) from Pratchett’s Discworld. Ankh-Morpork has Thieves, Assassins and ‘Seamstresses’ Guilds, but no Firefighting Guild.
Apparently there was one at some point bit they ran an protection racket the Mafia would have been proud of, standing around rich houses loudly proclaiming how flammable it all looked and what a shame it would be if it all went up in flames while not paid up to the guild.
