I will also accept a salon if you prefer more specialised hair care while you're being operated on without anaesthetic. It can be a tooth extraction, a trepanation, bleeding into a bucket until you're cured of an illness, or someone who has legally never seen the inside of a body- even a drawing- fishing around in your guts for a possessed organ with their unwashed fingers. Your antibiotics can consist of wine and bread.
i think barbers guilds-->surgeons guilds transition was around the same time as alcohol distilling was becoming available for medicine---so there can be anaesthetic its just the kind that makes you bleed to death
