Medical snobbery trends like this: Maximum snobbery as a pre-med, minimal snobbery as an attending. Its generally a linear curve. There are outliers sometimes, but this is how it usually goes.
Premeds have yet to experience the real-world. They think they are going into a profession (if their accepted, first of all) that is at the mountain of achievement, looking down at the rest of the world. It takes years of being told, and proven, that you know jack, that nurses don't care that your MS3 or Dr. whomever, that a 50 year old pharmacist with 25 years in the field doesn't give a damn that your some 28 year old first year hot shot who thinks your always right. By the time the doc has been through the gauntlet and gets attending status, they've learned.
I know this, because half the time I call an MD to discuss a script, they just tell me the situation and ask me for my recommendation, and I'm just an intern. This does not reduce my respect in a prescriber one bit either, and actually this earns them more respect, as their willing enough, and intelligent, to recognize a pharmacist's expertise.
