One extra thought about the night shop idea — it could be run by those two horny elf girls from the anime “S-Rank Monster Behemoth but Mistaken for a Cat” (Tama’s story).
They’re basically walking fanservice already, so working there naked at night would fit their vibe perfectly and give the location a playful, unique identity.
How to adapt them exactly — I’ll leave that up to you, of course. It’s just a fun option that could make the place stand out more.
