I do "de-uniform" myself whenever possible. But it's not always possible and it's not always effective. I will say, I've become somewhat blunt to the point of rudeness in my responce to questions just to shut them up if they insist of talking through my headphones (which is itself rude imo)... taking off the headset and asking them to repeat the question even though I heard them the first time, replying as quickly and with as short an answer as possible and putting my headphones back on before they ask another, and they sometimes do ask another after I put the heaphones back on and I do the same thing again. I don't think I've gotten more than two questsions doing that.
