Haha, I love the premise of this thread. People who love lording it over everyone that they are med students are so pathetic. Some people, amazingly, continue this attitude until well into clinical years and continue to believe that their existence on the earth is the single greatest and most important development in the history of the world. When they become residents they "suddenly" attain the realization that med students are inferior, stupid, and clueless and deserve to be treated as such. Then when they become attendings they discover that residents suck. If they end up going into a subspecialty residency they also discover that primary care physicians are stupid and clueless, and those in their specialty are the enlightened ones.
Don't worry though, almost all of you will be privy to witness a virtual beat-down of these self-entitled losers when they try to correct an attending during rounds, or they show up on the wards looking and acting like Osler reincarnated but then don't know where to put the sodium value in their electrolyte notation.
Unfortunately the sad thing is that once these people eventually become attendings, even if they have been schooled and berated, revert back to the original phenotype. They become the attendings who show up late but demand you be on time. The attendings who badmouth other physicians to patients and then get upset when someone marginalizes their little corner of medicine. The attendings who pick favorites with med students or residents they are evaluating based on something trivial. It never really ends. But the good news is that the farther along you get, the more you can marginalize these trivial empty white coats.
To be honest, one of my favorite things about finishing med school was that I didn't have to wear my white coat anymore.
As far as wearing scrubs in public, that's weak. Scrubs are supposed to represent the supposedly cleaner hospital environment. You can wear them outside of the hospital, but hopefully you are changing them when you arrive at work and start doing your clinical duties. What you should not do is what I have seen: The ***** surgical resident who wears his scrubs to the nearby diner, shoves his face with all kinds of food, and then belches his way into the OR without changing. It's fascinating that they allow people like this to walk into the OR and refuse to allow someone in a clean pressed suit to walk in. "I'm wearing scrubs!" Part of the reason MRSA is spreading is probably because people are wearing scrubs 24 hrs a day and not changing before they leave and after they arrive. That's ok though, because they look cool, right? 95% of people who never change out of scrubs are lazy.
