Often the MD suffix is synonymous with runaway ego.

I always thought Cadillac drivers were the same until I bought one, then I found
that other drivers make you that way. If one is deferred to often enough one
comes to expect it. After observing how folks treated his MD uncle a buddy of
mine began using it to his own advantage. For example, if you leave a message
for a friend he may or may not get it but if you say "Tell him Dr. Daniels
called about his lab results" he almost certainly will. The down side was he
was often asked for free diagnosis. He cured that by claiming to be a
proctologist!
