Obviously when you're talking it's different. I'm thinking of random foids just randomly giving supposed "looks of disgust" to guys they don't know.
I sense discomfort all the time, but it's not manifested as looks of disgust. More like avoiding eye contact at all cost, avoiding drawing attention to herself and giving me any reason to engage with her. The same way people react to beggars except beggars at least get money sometimes.
And not just me, sometimes I'll sit for hours in a sidewalk cafe or wherever and look at foids looking around and they never ever give "looks of disgust" to anyone.
