The tendency that Danny is exhibiting by finding the behavior of his host to be strange and his own way to be the correct way is called Ethnocentrism.
Explanation:
Ethnocentrism in sociology and anthropology is a term used for a phenomenon in which a person who has spent most of their life following a form of customs considering them to be right when faced with another form of customs and believing that the others are behaving irrationally.
It is characterized by the belief that whatever the custom was in the homeland of the person was right and whatever the others do differently is illogical and completely out of the normal.
