The man thinks he is so great. Yes, he is... in getting money. Don't expect him to handle anything serious. Instead of dentistry, he seems to have attended a school where they teach how to get money from patients, not how to treat them.
He does not even think that he has to treat patients, getting them to pay is enough. when something fails, it is not his fault and what is the problem! you have already paid, haven't you.
He tries to do everything in dentistry and of course he fails, because he is way below average.
Pros: ensures that you pay
Cons: does not ensure that you get treatment
