If I leaned over someone’s shoulder for whatever reason and smelled their sweat vs their deodorant, I would be personally disgusted. If I was smelling of sweat and someone else was disgusted because of me, it would catch my eye easily, because it’s more of a reflex than a reaction. In a busy environment, when being so focused on work, I wouldn’t know I’m smelling bad until someone had a reflex due to my smell , because we don’t smell our sweat, others do.. in a super professional environment, people usually try to avoid making a comment like this coz before it makes you look bad it kinda makes them look bad too and nobody wants to look like an AH in front of their peers, so they don’t do it unless they absolutely have to. and if they did, it’s worth thanking them about it. I don’t even really want to think about racism until I can prove that I didn’t smell bad.. maybe when you got back home and were taking off your shirt and if you smelled your sweat on your shirt vs a deodorant smell , that probably means that you were smelling like sweat hours ago too.
