Your rate really should have been $89 per night. That is exactly what the manager should have charged you upon discovering the "misunderstanding" (aka fraud) regarding your nephew's employment.

Instead the manager was nice enough to give you the room for $58 - meaning you still are ahead $31.

And now you have the gall to think you are entitled to something more? There is a great term for a person like you, but for me to use it would mean I would be banned from this site.
