I _always_ wear headphones and I don't recall anyone actually tapping me on the shoulder to get my attention, which is good, because that kind of thing can startle the crap out of me. Usually they have to resort to waving their hand in my field of view, but that works fine. Although I do wear headphones pretty much constantly, I have always made a point to be responsive to people and not ignore them. If someone needs my attention, they will get it, and I made a point of doing everything I can to help people. Yes, I'd rather not be disturbed, but if they really need my help, then I will gladly stop and help. This is no different than if I were in a cubicle or my own office. I have no problems with that kind of distraction. It's the unintentional distractions that we need to eliminate.
