It's the same way with sexism. It's not always blatant "wOmAn bAd"
I'd go to a mechanic with my ex to get her car worked on and everyone only wants to talk to me. I've worked food service where our cashier was a woman and people would deliberately only talk to me. I had a pipe burst at my roommates house but because I'm the man the water service guy only wanted to talk to me.
That last one fucked with me the most cause I'm like "dude, this isn't my house"
