I'm gonna go out on a limb and say I have forgotten more about the profession than you have learned thus far.
WVU gave the prime example on why you cannot just randomly call yourself a doctor. I should dig up a case I read about two years back for a CE in which a pharmacist, referring to himself as a 'doctor', had actually patients he was not aware he had. You see they had assumed he was an MD and actually switched to their 'new doctor'. One of them died as a result of complications from a medical condition their actual doctor was treating. The family sued and won under something similar to misrepresentation of character.
And judging from your previous posts, you're going to go "Well the public will be able to tell the difference."
Let me in on a little tiny secret that anyone has worked retail knows. The public are way more stupid than you can possibly imagine. This is not to say they are not intelligent, they just do not do the smart thing at all times.
Plus, it's, again, a douchebag thing to do.
When I'm done should I be referred to as Dr. Phathead, PharmD, MBA, CPhT, Master of the Universe everywhere I go?
If that's what you really think, you need to find another profession because I do not want to have to consider you a colleague
