Funny irony I've noticed lately: the farther away from actually being a doctor, the greater your desire to be seen as one*. The longer you've actually been a doctor the less you want to be identified as one.
This has been seen with the first years who are wandering around campus with their stetho's around their necks while doing BP checks for charity. Really, do you have to keep it there while you aren't even doing BP's? No. It just makes you look like a douche to those of us that are old, bitter, jaded have been around the healthcare block a few times.
I suppose it isn't as bad as scubs at the gym though, that takes the cake.
In social/public situations many of my doc friends either lie completely about their profession (common substitutes are 'computer guy' and 'video store clerk') or really downplay it. And guaranteed, on a flight they'll shrink to just below their tray table when the announcement overhead asks if there is a doctor on the plane.
I find it all very amusing.
*Or greater desire to be seen as a medical student.
