Well that's just stupid "Do it or I revoke your adventurer license"
Ok do it, you need their help more than they need the license, you're playing a losing game.
But naaah better go the stupid plot way.
I mean, even cheap ones will need fletching, even in real life with mass production arrows are still fairly expensive (like 2-3€ a piece) and actual hunting arrows are probably 5-10 times that price, with dungeoneering and monster hunting your odds of losing or breaking arrows are probably high.
No that actually makes a lot of sense, entitled egomaniacs would never give a single shit about him, they live believing they're owed it. Beside in chapter 1 they definitely showed that low rank healer girl for a reason, and even that Ganache guy(?) seems ok, maybe not nice but didn't seem to be...
"I won't let you play the executioner" Surely not a stupid ass decision that will definitely not bite them in the ass later on, it's not like Slad is a saint that has never killed, it would just be one more.
Same I hate that, like "Genderswapped Medic's Battlefield Diary" Her formerly being a man has had 0 impact on the story, and without reading the synopsis again I wouldn't even remember she was a former pro fps player, and I'm not even sure the Isekai itself has had any relevance at all.
