That's too bad.

It'd also be hard for the DM to handle a player character who suddenly goes off to retire, and end up peddling mystery bird roast.

If I were DM though, I'd probably ‘promote‘ that guy to ‘recurring NPC’. I'd have that NPC randomly show up whenever the party decides to long rest, offering a selection of mystery meat for ridiculously low prices.

I could also have that guy sell potions and stuff at a ridiculously high markup, lol!
