entitled (adj) — sense 3

THE STRAIN OF DEALING WITH ENTITLED PEOPLE. Dealing with people who are generally convinced that life (and, in particular, the clinician) owes them something can be very wearisome work — particularly if on some level (usually unconscious) the clinician believes it is appropriate (and necessary for a feeling of competence and self-worth) to satisfy this special need. […] Entitled people can be even more difficult when they have the resources in the form of prestige, power, and/or wealth to transcend the usual bonds of social reality, or when they have the bitterness and tenacity to use legal action in the face of real or imagined failings on the part of the clinician.
