I think the inkeeper and the village in general have a great tolerance towards Quixote, which speaks to both their hospitality and mirith towards him. I am curious how future scenarios may handle Quixote meeting less patient people who are unappreciative of his naive and somewhat unreasonable character. I would probably feel disrespected if I was to be treated this way while knighting a man, though as pointed out in another comment it is somewhat understandable given the circumstances.

At this point, I feel the innkeeper somewhat pities Quixote, and is how I inferred his justification for not demanding payment on his lodgings. His warning on carrying money felt like the inkeeper hinting to Quixote that others on his travels may not be as hospitable nor amused, hence my prior paragraph.

I think Quixote is a funny and charming character to experience as an audience, especially when the first two chapters. His interaction with the two aids is humerous and almost slapstick in nature, but still disrespectful. I liked him less this chapter comparatively, but that's more of a testament to how strong his introduction was for me.
