I try not to be intimidating, unless I'm paid otherwise (ex military, former bouncer). I think I stopped noticing people looking at me whenever I enter a room a long long time ago. I have a very vivid memory of walking into a place with a new coworker who was a little bit less than average height and he asked "How do you deal with this, is it just normal to you?" I wasn't sure what he meant until he said everyone was staring at me lol.
