Yeah, I got alot of that during 3rd year as well. I think it's because of what Ortho2003 said. I always tended to cut to the chase as far as pt. management. While the med resident was saying "Hmmm, better get the left-legged papular rash consult", I'd usually ask something like "so how come we don't try this first?" I also was usually a little scimpy as far as the length of my notes and presenting patients. I was always thorough, but my notes were always a little shorter and to the point.
I never really took it as an insult, and I don't think it was meant to be. It's just different strokes for different folks. Don't sweat the comments that don't mean squat in the end anyway.
