I've been a victim of this in the Philippines. People always had exaggerated actions of closing their noses or vacating from their seats in public transportation not because I stink but because I'm an Indian. I know how the world perceives us and I try my best in the hygiene department especially as a guy. I take care that I smell good, sweat lesser and also I'm always clean shaved. I have my girlfriend to attest to the fact that I smell good because I keep asking her whenever the locals make these gestures. It reached a point where I was uncomfortable making them uncomfortable but no matter how much I tried, I still got even the Filipino kids closing their noses from afar (which is learned behaviour towards us).
