It says that Mudcat "mirrors" the real world, with real people, with real feelings.

In the real world you are expected to behave in a certain way to a GUEST but the guest also has obligations in the way that they behave.

If, as a GUEST in my home, you behaved in a way I found unacceptable, you would be asked to leave because you had been so ill-mannered as to take advantage of my hospitality.

Max is a very generous and benign HOST but that does not mean that his hospitality can be abused.
