| Snopes considers it undetermined although the call was indeed a genuine one made to the Orange County Sheriff's Office.
From the article, the caller: "fulfills all the stereotypes of the narcissistic, pompous, self-absorbed Orange County soccer mom as she berates the restaurant employees for screwing up her kids' order and ignoring her, and the dispatcher for refusing to send an officer out to deal with the situation (a reasonable expectation, she maintains, because the police are "supposed to be here to protect me")."
Having worked in law enforcement, I can attest to this kind of behaviour in people. There is a certain percentage of the populace out there that are that full of themselves. This is why I have an easy time believing the caller was sincere.
Some of the visitors that showed up at the prison were excellent examples of a waste of oxygen. |
