I've done coding and other laptop work in coffee shops many times, and I'm usually acutely aware of my surroundings and people around me. I've never noticed anyone staring at me in a coffee shop. Are you doing something unusual to bring this attention on yourself? Or do you live in a place with jerks? Also, what ethnicity were the people staring at you? Some cultures (like Indian) don't have the cultural aversion to staring that westerners do (though usually ones who come over here figure that out pretty quickly and stop it).
