I was being sarcastic about the investment banker comment, and I shouldn't have worded it as "flashing" the MD badge like some sort of an FBI agent, cause I didn't mean that literally. I just meant disclosing that you are a physician. Anyway, I am very new to the whole posting in forum things, so I forget that I have to be careful on how I word things from now on. I should probably go back to being a lurker

Oh, and for the record, I never "flashed" my md badge ever and I rarely disclose my profession to anyone in public. I usually just say I work in a lab if someone asks. But I posted this question in the first place because I thought maybe the one time I would ever do it is to get a airline perk, because a lot of people in other professions seem to get perks like that with their line of work and extensive travelling. I guess it was a little selfish of me to want to have a little special treatment too now and then.
