i don't have this problem. i have resting i'm going to eat your face face.
cashiers, for example, avoid eye contact and won't initiate conversation.
mostly i'm fine with it. i usually hate talking to strangers.
oddly, about one in 100 people sees straight through it. my wife, for example, finds me completely unintimidating.
but back when we used to work together, people would actually go to her when they had questions for me because they were afraid to ask me themselves.
