Sam could handle trying to reason with a few people to leave. Or get rough with them if he has to, though that would be last resort.

And he'd be open to working with others to do this for Miss Yuka too! Since the money and the meal wouldn't really be the motivation for him so much as 1) helping, 2) making an acquaintance of Miss Yuka in case anyone he knows ever shows up at the Inn??, 3) discovering the types of creatures that stay at the Inn.
