And corresponding Delusion of Relevance.
These "fu**in DOCTORS" aren't well known for being financially savvy. Some are, but most are exactly like this dipshi*. They are arrogant a-holes, and they can never get along with their partners who are always other doctors. And wile they smile and make nice with their patients, they also treat their employees like absolute garbage behind the scenes. I've seen them have these girls to the point of crying. When I have to deal with them directly, they often try this exact "I'm a doctor" crap on me, and they are generally left somewhat speechless when they get the "and I'm the security guy, doctors aren't allowed to do that either". Man, I could tell some stories, but I'll refrain because it's inside business stuff and clients.
IF PCIngrate even really is a doctor, it says a lot that he's 72 and can't pay his bills without getting a part-time job. If I had to guess, he's on his 4th wife, insists on driving a cheap Porsche with a 1500/mo payment so he can park it next to the others in the lot, lives in a townhouse on a canal, and is in debt over his head due to his inability to manage his money and stop getting it all seized in divorce battles.
These guys are almost like cookie-cutter a**holes... not unlike many lawyers I've had to deal with. They have a really inflated view of themselves as a general rule. Don't get me wrong, maybe 10-15% of them are actually good people who defy the caricature outlined above, but they are the exception.
